Just to drop you a note to say that the work you did on my Mercedes CLC on Sunday worked a treat. Previously it was not smooth on gear changes and made it a grueling experience on round-abouts and picking up and also made the engine quite noisy under acceleration Within a few miles of driving away after our conversion I noticed the car was much smoother, changed up much, much quicker and stayed in a higher gear longer without struggle. My motorway trip home at 70! I was happy to see a constant 37 MPG from the on board computer. The car is completely different and the work Steve has done is fantastic, he knows how far to push the car and recommend a safe power gain for economy and performance. I will definitely recommend Steve’s SRS Performance. Thanks, Ritesh

Hi Steve Many thanks for “waking up” my Golf,I’ve had a grin on my face ever since you re-mapped it.The difference is truly remarkable. Not only is the the car much quicker, but much smoother in it’s delivery of that power, with the welcome bonus of better fuel consumption. The whole experience was also very enjoyable. I will, of course be recommending you to everyone that I know.

Golf 2.0 TDi
Hi Steve, I\'m really pleased will the remap, it has made a big difference to the way it drives. No more holding up traffic on the hills. It has made it like the way it should have been made in the first place, and is quite a pleasure to drive. I have now been on two trips away since the remap with no problems at all. It will probably be the best money spent on the motor home, and I will recommend you to any one thinking of a remap. Many thanks, Carl

Hi Steve Can\'t tell you how pleased I am with the re-mapping,the car runs smoother than ever up through the gears,has a lot more power and better mpg.Its like driving a different car,can hardly believe the change.Thankyou

I booked in with SRS Performance to have my Nissan Navara remapped. I explained that I specifically needed my car for towing my caravan. My Navara has an automatic gearbox and was struggling slightly, particularly on hills and was constantly changing gear to accommodate. I wasn\\\'t sure what to expect from the remap. I just thought that it would be a little bit faster and a little bit more powerful. How wrong could I have been. After the remap I took the Navara for a test drive. I thought that I would feel no difference in the performance. But it was like driving a two and a half ton sports car. The acceleration and handling was amazing. It was like driving a completely different car. I was really impressed. I arrived back at Steve\\\'s and tried to hide the massive give away smile on my face when I joking said "There's no difference". Before the remap I could have read "War and Peace" before I got up to 60 mph and I would really have had to put my foot down burning loads of diesel in the process. Now, I hardly touch the accelerator and it flies along. I haven\'t towed my caravan yet. But we go away in October to Hereford where it\'s a little hilly so I am looking forward to experiencing the difference in my Navara. Thanks again Steve. I will definitely recommend your services to my friends.

Steve, thanks so much for giving my trusty Saab a new lease of life. Now it runs effortlessly and almost silently. In town I hardly have to touch the throttle and on the motorway I have all the confidence of more than sufficient power in reserve. Who'd have thought it? 45 extra bhp AND 10% more mpg! Guys - get Steve to re-map your car - it's a no-brainer!
Francis from Stratford

HI Steve. A big thank you for your time and expertise in resolving the problem with my car, after being left with a car that was smoking all the time on idle from a previous remap I was beginning to believe that it would cost me more to put it right than what it was worth, then I found SRS Performance. So many other people had tried to diagnose the fault and put it right, but failed, right from the start you advised you would only advise me if you were sure that you could solve the issue, your knowledge and understanding is unbelievable, so much so that my husband is now thinking what you could do with his Audi
Michelle from Coventry

Great service from Steve who was very thorough checking over the car prior to writing the new map. He saved a copy of the original map, identified and cleared erroneous faults and emailed me a list of the remaining faults that didn\'t clear together with both the old and new maps. The mapping process took a couple of hours including the test drives and it was all done on the same day we contacted SRS Performance. Steve was very careful when installing the new software and he test drove the car before and after mapping, he even identified a fault with one of the shocks during the test drive. My TT is now far more powerful thanks to the SRS Performance remap. It\'s much easier to get up to speed and therefore easier to drive. Don\'t really know how but the MPG has improved too. Overall the SRS Performance map has turned up the grin factor by 100% and made my TT more exciting to drive now than when I first got the car 10 years ago. Many thanks to Steve who was a charming man and extremely enthusiastic about getting a girls pride and joy to perform better. Kindest Regards Paula
