How long does the remap take and how soon will I see results

Performance remapping for BMW 435d 3.0 313-BHP can take anywhere between 90 and 120 minutes, depending on the technical aspects of your vehicle. It is recommended that you allow 2-3 hours as we like to go through everything with you so there are no questions later on. 

The results of your BMW 435D remap will be immediate and impressive, and typically customers report even more notable performance over the next 200-300 miles too. 

You can look forward to an increase in power that feels linear throughout the rev range. 

More power means more fun—and performance remapping gives you both.

Will I notice an improvement in fuel consumption

A professional remap is a huge boost in terms of power, torque and driveability but it won’t negatively affect fuel consumption. In fact, a professionally tuned engine tends to use less fuel as it has been adjusted to make better use of air-fuel ratio and ignition timings which improves efficiency.

Although we cannot guarantee any particular gain in MPG, typically customers enjoy between 10-20% better MPG, but of course, this is also subject to driving style, traffic conditions, servicing etc.

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.

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.
