Warning by MPG Tuning - Fake ECU Remap Scams

Warning Buyer Beware ECU Remapping ChipTuning Scams

Have you ever been reeled in by low prices, and then discovered that you haven't had the service you was expecting?

If it sounds too good to be true, it probably is. I’m sure that you’ve heard the phrase, “you get what you pay for”.

Recently, I did a bit of research into our ecu remapping competitors, and there are many. During my search, several operators’ low prices caught my eye, all with fantastical power gain and MPG claims.

On the surface their proposed service looks great, but read a bit deeper with an experienced eye and you will see that all is not what it seems, or indeed they would like you to believe.

For the inexperienced remapping is like a black art  Due to a lack of experience, potential customers, often take the bait of an alluring deal only to be left utterly frustrated in the end.

Please stay with me, and I’ll explain. Imagine you have heard about remapping and its various benefits, so you begin your Internet search for the best remapping deals in your area.

Great Sounding Remap Deals – Lure you in

There are some remap companies that offer seemingly fantastic deals. You may have searched online for a company offering professional tuning services. Or, perhaps you saw an advert by a remapping company promising “industry leading” power gains and even the promise of a live or dyno tune.

Remember These Words

With “too good to be true” remap deals, here are two words that you should remember: buyers beware.

Snake Oil - Look for Red Flags

Red flags for remap companies include claims like “ The UK’s Number One” Tuning Specialist or “Live Remaps”  or the promise of unrealistic power and MPG gains.

“The UK’s Number One.” Says who? Any individual or company that claims to be number one “Unless they have been voted number one” by an independent and recognised organisation, is bullshitting you!

“Live Remapping” On a standard production car with stock ECU, there is "NO Such Thing as a Live Remap” or a "Dyno Remap".

The term Live Remap relates to the car being driven on the road or dyno while having the engine management data altered, this can only be done with the engine running and is not possible without an aftermarket or piggy back ECU.

Immediately someone tells you they do live remapping or that a remap on a dyno is in some way superior, turn your bullshit deflectors on!

There are technical limitations and mechanical safety factors that have to be observed to have a happy outcome.

Read the reviews

The best reviews to consider are on a medium like facebook or similar, where the page owner cannot edit the feedback, and unless they have a lot of friends who can leave fake reviews, most of what you read is most likely pretty accurate.

Read the 1 star as well as the 5 star reviews

Why have people left 1 star reviews is it because they are competitors (yes that’s possible) is it because they are trolls (yes that’s possible) but on the whole it’s because they are not happy for one reason or another, so make sure you read them as well as the 5 star to get a good measure of the the remapping provider results.


Most websites or pages I have seen make a big deal about being insured, but is it the correct insurance cover? In my experience even tuners that do actually have insurance, don’t have the correct type of cover so if something does go wrong, you’re not actually covered anyway.

Mobile Remaps

There have been unethical practices by so-called remap professionals that have given the industry a poor reputation. There are some good mobile remapping providers, but nowadays that is more of a rarity. To offer a high quality, correctly insured service professional remapping companies have to make huge investment in equipment, software, insurance, premises, training to mention a few. Some people see remapping as a way to make a quick buck, and can unfortunately get in on the act for little or no real investment...

Typical costs to someone setting up as a mobile remap provider, on the cheap
  • No cost of premises
  • Buy cloned tools for as little as £40 off the internet
  • Buy so called tuned files off the internet for as little as £10
  • Operate from a mobile phone only (can replace it when it gets too hot with complaints)
  • Cheap or low cost website
  • Charge as little as £100 for a remap
  • When things go wrong they are nowhere to be found
  • No need to worry about reputation just get a new phone

Do you want someone cutting corners like that working on the brain of your car?

Here are a few tips to keep in mind
  • Beware of offers too good to be true
  • Watch for red flags
  • Read the reviews – Good and Bad
Realise that we get what we pay for. The least expensive option is not always the best

Choosing a Good Tuner is as important as choosing a Good Doctor.

You will be presented with a bewildering selection of companies, all claiming to be the best in the industry. Unfortunately the industry has been flooded with “Get Rich Quick” merchants all desperate to take your money from you. In many cases the “Get Rich Quick” operators have invested in “Cloned” counterfeit remapping tools off the internet. They have little “if any” industry knowledge, experience or liability insurance…

Don’t get sucked in by a good story and what appears to be an incredible price. Instead of taking the word of self-acclaimed tuning experts, a search on google will reveal some very interesting, yet disturbing facts about a few “so called” professionals. Unlike some testimonials “Bert for Bognor says we are Brill” our customers are real people. Don’t take our word for it, ask the people that know best “Our Customers”

Had my Audi A3 mapped by mike last week and the power and mpg gains are Insane! This is the 7th car Mike has tuned for me over the last 10 years for me so that speaks for itself. Had 1 other car remapped by a different tuner and the results were poor compared to mpg. See you when I get my next car.

Steve Taylor

Mike has done a brilliant job. Had both mine and my wife’s cars done and after a 20 mile drive, the difference is obvious. Power delivery is like a very different car. My Astra 1.8vvt used to have a couple of flat spots, now they’re gone, it is now a smooth delivery with lots of power all the way through. My wife’s 1.6vvt now feels more like a 1.8 and her fuel economy has improved by 10mpg, mine by 5mpg. So definitely worth doing, even on N/A cars, the remap has improved drivability so much.

Paul Harrison

I took my wife's little 1.2 normally aspirated corsa to see what could be done as it seemed a little flat on the uptake.. Great service ..all questions answered in as much detail as you can understand what the process is going to be ... The difference was brilliant... a lot smother on the uptake with a little pep to get it off to a good start ... Friendly ... good knowledge of the industry & would recommend for sure Thanks a again for the great service ... keep up the good work Many thanks Ian

Ian Hancox

Took my tired VW Golf 2.0TDi mk6 to Mike hoping he could give the lackluster engine a bit of life, boy was I in for a pleasant surprise! Mike listened to what I was looking for, booked my car in and got on with it. Once completed we went for a test drive and i could immediately feel the difference. My car pulls away pretty sprightly but then as the turbo joins in the car feels like its going to take off. Most impressive difference is mid range to high range rpm accelleration, like from 25 to 70mph,its just so quick now.

Craig Cousins

Had my Renault Clio RS 200 2.0 remapped. What a brilliant experience, brilliant guy and brilliant results! I would 100% recommend this company for you. I had low down deficiency in power due to the natural aspiration type engine my car has, afterwards it was straight on the power. he gave me a custom map to suit me with more power mid-hi level revs as well as low down and I can really feel the difference through the gears. Fantastic experience overall, extremely pleased!!!!

Connor Roberts

First just to say a big thank you. Started the afternoon with a warm welcome and a nice cup of coffee. Had a really good chat and then a really good map put on to my ecu. (Mg Zr 1.4) used to hit a rev limiter at about 6500rpm. Now nearly 8000rpm. And pulls like a train. Once again thank you.

Lee Fletcher

I went for a remap on my T5 as it had a awful flat spot around 2800 rev's I got great personal service and its like having a new engine in the van smooth power and greater economy.... Highly recommended wish I'd done it months ago it would have paid for it self already thanks a lot hill's are no longer a drag

Adrian McManus

Popped in to see Mike on Friday to have my A4 2.0TDi 170hp remapped. Have to say I was a little pessimistic at first having being told by another firm that remaps on these were a nightmare so was expecting the worst! Thankfully, nothing of the sort, straight in, one error message unknown but Mike worked it out and all done in no time. Straight out for a test run and the drive is very different, certainly mid ranged (where these engines seem to suffer) pulls away nicely and can definitely feel the benefit. Best money I've ever spent on a car in, well, forever! Thanks again Mike

Mark Patterson

Absolutely brilliant! Took my Ford Fiesta there and ask for a power and acceleration and boy did I get it, didn't expect to notice that much of a difference from the 1.2 but my god I have, normally up hills I have to change down a gear and now it just pulls and pulls in 5th, acceleration is so much better and I'll be taking my 2.0 golf there when I buy it, thanks Mike and what a great brew maker he is!

Ceiran Linton-Bird

Had my 320d remapped by Mike yesterday. Very impressed with the results. Noticed it straight away after having it done. Service was also great, talked me through all of it to get exactly what I wanted out of it. Highly recommend mpg tuning.

James Aston

Took My Saab 93 into Mike. He explained the process and what he was going too do. Consulted with me to see what I was after and started work. The car now feel as it should have all along, responsive, no flat spots and better MPG too boot. Mikes an honest down to earth guy and I would most definitely use him and recommend him.

Josh Neale

Took my Civic Mk VIII 2.2 CDTI to Mike following a recommendation from a friend who's had his last few cars remapped at MPG., professional service and answered any questions I had. Customised remap that gave me a good balance between performance and economy. Mike was happy to let me watch the whole procedure and explained what he was doing. Makes a good brew as well! Would highly recommend, Will definitely bring my future motors here.

Dan Wright

Had my remap done here at mpg on Audi a3 2.0ltr tdi I wasn't expecting it to be that much different, went for a test drive afterwards and I was really shocked at the difference in throttle response and power is amazing. My turbo kicks in earlier and now pulls much better in every gear and really good value for money thanks mpg really happy.

Steve Willis

Just had my BMW 320d remapped and it is absolutely superb the power is unbelievable and the service is outstanding would recommend it to anybody he has transformed my car from 160 bhp to 207 bhp no smoke at all and the power delivery is awesome throughout all of the gears really happy

Tom Dawson

Took my x reg fiesta zetec s into mpg two days ago wow wot a difference was sluggish and some faults it's like sh## of a shovel now drives a lot smoother doesn't try to stall when stationary I'm over the moon very nice chap and great service. best time and money ever spent on a car thanks again mike

Steven Fluff Kelly

Had my Astra 1.9cdti remapped here with EGR delete for a great price, I have now got the full power and yes it's rapid lol.... Mike was helpful and talked me through it all and also good after care as well. Thanks again

Scott Walker

Brilliant service, absolute cracking guy very understanding and helpful. Went thru the whole process with me explained everything in detail would definitely use again and recommend to anyone Great cuppa and my cars immense, Can't thank you enough cheers Car: Peugeot 206 2.0HDI 90hp - Dan wanted me to turn this car into a Ferrari, which obviously we couldn't do but were able to improve power considerably and certainly to Dan's satisfaction.

Dan D Man Startin

Although they where unable to suit my needs due to my car they have gave me a lot of information about the market and are willing to offer help to avoid cowboy traders, a company that genuinely cares for customers and will offer help to non buyers is a massive plus in my eyes and should be highly trusted

Keiran Orchard

I took my vauxhall astra gtc sri into Mike at mpg, nice genuine guy, talks you through everything he does and does a brilliant job! The difference in performance is noticeable immediately after seeing him!Highly recommend anybody to go to him for a genuinely good and safe remap! Thank you mike!

Jay Smith

A 5 star company had the map on my car for over a month and still putting a smile on my face when giving it some. Highly recommended will definitely use again in the future
