So You Want A Remap, Read This First!

So you want a remap but are worried about who to use and want to know that your vehicle will be ok after the remap?

Will My Car Still Work After The Remap

That depends on a few factors, a few are listed below

  1. What condition is your car in?
  2. Are there any faults in your car?
  3. Are any parts near the end of life?
  4. The quality, reputation and experience of your tuner.

Near End Of Life
Near the end of life parts, can work perfectly well on stock tune, but fail due to the extra demand made on them by the remap (although this is rare with a good remap, it can and does happen). This doesn't automatically mean the remap is bad.

Pre Remapping Diagnostics
You would expect a reputable tuner to run a detailed diagnostic test to highlight any issues, but you also need to understand these Facts


Diagnostic Tools Are Useful Guide but They are Not A Magic Wand or a Silver Bullet

  1. Even the best diagnostic tool available can only highlight any issues stored as DTC's on the ECU.
  2. Even the best diagnostic tool will not report "certain" aspects of vehicle condition.
  3. Even the best diagnostic tool is not a fortune teller and cannot predict faults that might occur at some point in the future.

What Can You Do To Reduce Remap Associated Risks

  1. Carefully research the tuner you want to use (if you simply select the cheapest price, you are asking for trouble).
  2. Make sure your chosen remapping company has good customer feedback.
  3. Do not use someone that you can only contact by mobile phone (what happens if you have a problem and they block you).
  4. Don't use someone that claims to be a professional but only charges £150 (a true professional cannot operate at those prices)
  5. Make sure your car is well serviced at a garage you trust (not all cars that are serviced have actually been serviced "shocking but true")
  6. Accept that issues can arise post remap and keep an open mind until any issue has been identified.

If you think a professional is too expensive - this will give you an idea of the differences between an amateur and a professional

A customer asked me how much it cost to do this job...
I answered him: £1500
Did he say: So expensive for this job?

I asked: How much do you think it would cost you?
He answers me: £800 maximum... That's a pretty simple job right? !"

  • For £800 I invite you to do it yourself.
  • But... I don't know how to.
  • For £800 I'll teach you how to. So besides saving you £700, you'll get the knowledge for the next time you want
  • It seemed right to him and he agreed.
  • But to get started: you need tools: A welder, grinder, chop saw, drill press, welding hood, gloves etc...
  • But I don't have all this equipment and I can't buy all of these for one job.
  • Well then for another £300 more I'll rent my stuff to you so you can do it.
  • Okay, he says.
  • Okay! Tuesday I'm waiting for you to start doing this work
  • But I can't on Tuesday I only have time today.
  • I'm sorry, but I'm only available Tuesday to teach you and lend you my stuff. Other days are busy with other customers.
  • Okay! That means I'm going to have to sacrifice my Tuesday, give up my tasks.
  • I forgot. To do your job yourself, you also have to pay for the nonproductive factors.
  • That is? What is this?"
  • Bureaucratic, tax, vat, security, insurance, fuel etc.
  • Oh no!... But to accomplish these tasks, I'm going to spend more money and waste a lot of time!
  • Do you have them? You can do it to me before?"
  • Okay!
  • I'll make you all the material you need.
  • Truck loading is done Monday evening or Tuesday morning you'll have to come by 6 to load the truck.
  • Don't forget to be on time to avoid traffic jams and be on time
  • At 6??? Nope! Too early for me! I am used to getting up later.
  • You know, I've been thinking.
  • You better get the job done.
  • I'd rather pay you £1500.
  • If I had to, it wouldn't be perfect and it would cost me a lot more.

When you pay for a job, especially handcrafted, you pay not only for the material used but also:

  • Knowledge
  • Experience
  • Study
  • Tools
  • Services
  • Time to go
  • Punctuality
  • Accountability
  • Professionalism
  • Accuracy
  • Guaranteed
  • Patents
  • Sacrifices
  • Safety and security
  • Payment of tax obligations

No one can denigrate other people's work by judging prices.

Only by knowing all the elements necessary for the production of certain work can you estimate the actual cost.

I did not write this dialogue but am sharing it to support craftsmen and entrepreneurs.

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”

I went for a remap on my T5 as it had an 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 hills are no longer a drag.

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

Had the ECU 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 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.
