MWR Performance Remapping

My first map with MWR transformed my car's performance but the gear change was intermittently harsh during mid-input acceleration ( itwas fine if going really easy or if driving it hard). I raised my concerns with Mark and he came back out to tweak it. It now drives amazing! Effortless performance and crazy torque. Great job!

Had my BMW 116D remapped yesterday. I can honestly say on my drive today, i took it for a nice run on some carriageways and you can clearly notice the difference. Even in eco mode it feels like it is in sport mode lol. Double the power and speed you pick up in a short amount of time is insaneThank you guys

Mark came today to remap my vw caddy van such a great down to earth guy, being only 75bhp any improvement would be an improvement. once mark had finished my van felt like it had been set free so much more responsive a completely different driving experience from what I’m used to the van has finally found it’s missing horses. Top man

Just been out for a test run in my Fiat Ducato based motorhome after Mark from MWR Performance did a stage one remap. What a difference!The extra power and torque means less gear changing and a more relaxed drive. Well worth the money. Would highly recommend.

Hugo B.

14:50 30 Apr 22

Highly recommended, both in terms of the ‘end result’ as well as the quality of service Mark delivered - work was done the week after I made contact, and he went (several!) extra miles to get the right kit needed for the specific job. Excellent stuff.

Mark remapped my audi a6 on the weekend and I'm very chuffed with the outcome! The gains are incredibly noticeable! I must admit I was a little skeptical and wasn't sure I would notice a difference but after going for a little rip I could instantly see the difference! R.i.p 55mpg 🤣🤷‍♂️Much appreciated, James.

Mark did a great remap on my Audi A3. Performance has improved massively! 👍 paid via installments which is really handy.

MWR Performance are a top notch professional service. Paul arrived right on time and worked efficiently on my Audi A6 ultra black edition to produce the results they guaranteed. I opted for the Stage 1 ECU remap, Paul successfully increased the horsepower by 35 bhp and the torque by 70nm. All of this without triggering not one single ECU fault. He even advised and waited for me to go for a test drive before leaving. I’m now receiving amazing performance, even better than expected. I’m sure there are cheaper quotes for remapping but this was definitely worth every penny. Great work Paul! 🚗💨👏🏾

Kevin G.

18:10 03 Mar 22

A great service with clear communication. The performance was exactly as advertised for my car. I’d recommend Mark to anyone.

I was sceptical about car tuning but a mechanic friend recommended Mark and I have to say that I’m not disappointed with the results. Car feels a lot more responsive with a much more linear power delivery.Thanks very much

I had a EGR delete and remap on my 09 discovery 3, the car is now running as smooth as ever and a noticeable power gain, would recommend Mark to anyone looking for this service.

Really good performance delivered from this company.My car feels great after the remapping i am really satisfied. Recomended!!!

You pay for what you get in life and I’ve used Mark a few times now - every time the service and remap have been superb. Tonight I saw first hand how mark prides himself on the level of customer service he gives. Mark came earlier in the day to remap my Mercedes’ e class. Later that evening, I encountered an issue with a warning light that appeared on the dash. I gave mark a call, explained the issue and he drove out all the way from Brighton ! What was even more incredible was that it was the night before he went on holiday. There was No issue - no moaning - he just drove out to see me to resolve the issue which he has done. Mark was also Insistent that we went for a test drive to make sure the issue didn’t happen again which is didn’t. So, think hard before you go for that slightly cheaper quote - would they offer this level of service. I doubt it !!

What a great service! Not my first experience of a tuning service provider and the two experieces could not have been more different. Mark was great and obviously has a wide mechanical knowledge. Left me a very happy customer. The Stage 1 tune is just what I needed, not about tearing down the road, but making the driving experience better, higher and better torque delivery. Would recommend MWR without hesitation.

Gary W.

17:54 06 Dec 21

Excellent service from Mark today regarding my vw polo definitely noticed the difference would highly recommend.

Finally decided to have my Renault Kadjar 1.6 dci remapped, after some research came across MWR. From 1st contact, booking and following communications Mark was very responsive and professional and kept me informed on eta on the day.Mark is very knowledgeable and highly experienced, he quickly got to work on the car and with his high tech equipment and extensive database soon had the remapping completed and ECU reinstalled and systems fully checked with no problems, even after dark!Really pleased with the quality of the mapping, the Renault is now up from 129 to 160bhp and 320 to 380nm and upgraded K&N air filter also adding to the overall package,. On initial testing instantly noticeable difference in throttle response and available power.A further longer 200 mile coastal run, I was really impressed with the overall driving experience, it really feels like a different car. Great power available through the gears and pulls strongly right through the rev range. The increases in the torque power was equally brilliant making motorway overtakes effortless, even in 6th gear. MPG was also improved returning well over 50mpg on the return journey. Local shorter journeys are still in the high 40's.Great work Mark, thanks again.I highly recommend Mark @ MWR and will definitely be using for all future vehicles

Mercedes 220 CDI 2013.Mark has been excellent throughout. Good communication and very efficient undertaking mobile ECU Stage 1 Remap.Increased Horsepower from 134 to 170 BHP – Increased Torque from 340 Nm to 400 Nm.The Power Delivery & Torque performance is really notable. In real world performance- torque at 400 Nm is just great …. Driving experience is really enhanced. Just do it. I really recommend it. Mark is super knowledgeable.He particularly likes working on Lamborghini’s. If he can do that - I was happy for him to remap the humble Merc ECU. Thoroughly recommended. October 2021.

Mark was really friendly and easy going. Even though we had some issues about meeting up. He was very helpufl. The remapnis worth every penny. A massive change to my 430i's performance. It's incredibly responsive, and feels very nimble. Honestly really can't stop grinning about the change.

Had my T5 102 mapped by Mark. Difference it made was night and day. Felt like a different van so much easier to drive, smoother and quicker.Great service, highly recommend and i will use him again. ThanksHi, just a bit feedback. After using my van for a few days and a trip up to London yesterday the difference is unbelievable. Motorway driving is so much easier, and it actually is better on fuel, guess it's because it dont need driven as hard to get it moving/ stay at speed. No more struggles on hills 😀.Thanks Again

I had my vw touran remapped, I really just wanted a little bit extra from the 1.6 diesel. When I drove the car for the first time I was very pleased, well worth having it done. I am 65 years old, but now I think I will start wearing a basebal cap and drinking red bull !

I was very apprehensive on getting a remap for my car because of so many company’s and stats out there on the web. Until I had a recommendation to this company! The online chat was first class answering all of my questions and queries about the remap how it would affect my car etc. Mark came out to do the map and he again was 5 star giving all the information needed. Quick easy process with the best price for maximum results! I can whole heartily recommend MWR Performance! If your looking for a remap then no need to look any further!I know who I’ll use in the future as well! 👍

I’ve had a few cars mapped by these guys in the past, always a friendly and professional service, they arrive on time every time and always deliver an exceptional service! The difference in the way our cars have driven after being mapped is phenomenal... smooth power delivery and always an improvement in fuel consumption too.... we would never hesitate to recommend these guys to anyone thinking of having they’re car mapped! Keep up the good work guys and see you soon for the 530 �

Had to reschedule my appointment due to unforeseen circumstances but they were nice enough to give me a discount for the trouble! Had my E220 amg done by mark and he went through the whole process which was great. Response and torque is ridiculous!! Highly recommend to anyone who wants more power/torque and even better on MPG! At a reasonable price too.

Hello all, just had my seat Leon re-mapped by mark (a very professional nice bloke explained the process and knew what he was doing) was a little sceptical at first as only seen the company advised on Facebook but now I've had the remap done could not recommend them enough my car is nothing like it was the turbo boosts a lot faster seems to be know turbo lag (like before) and puts the power down a lot faster very happy 😁 Many thanks to you all great job 👍🏼

Stuart I.

18:37 05 Apr 17

I am the proud owner of a 3.0D Sport X5, then Matt sent Mark over to remap my car. All I can say is the wife said I was grinning for hours after I took it for a test drive the acceleration and pull through to gearing is mind blowing. The process took no time to complete and the outcome is extraordinary. This process comes highly recommended.

I had my S type jag remapped today by these people and have to say I'm very pleased with the results, very professional and courteous, arrived on time and talked me through what was going on, the outcome being my diesel jag is now putting out a very nice 258bhp and 534nm of torque, in the sports mode it's now a beast instead of a calm big cat so many many thanks to you I will def be recommending you to others, oh and the pricing is very gentle on the pocket compared to other companies and these guys come to you�

Daniel S.

14:11 26 Aug 16

Great service, friendly people and above all amazing value!My van now happily pulls the heavy loads I carry on a daily basis.Throttle response has improved and the power from my turbo now doesn't die out after 3,000rpm.I would highly recommend, and will be to friends and family �
