Took my BMW 640d here for a stage 1 remap. What a transformation to an already good car. I now have a lot more power with a far smoother delivery. Feels like a totally different car. I will definitely recommend having your car remapped here, a friendly and very knowledgeable guy.- Mark from Sheffield 21/01/2019
Did my research and dropped in at SLT, was given an appointment the very next morning first off. Talked me through it all prior and checked for any faults or issues prior to mapping. To my suprise I was told the car had a map already installed by another company which was eating fuel. SLT straight away got rid of this and did a proper job. Car is transformed, smoother to drive, punchier and the fuel economy is brilliant now. Thanks again from one happy customer.

Took my Skoda Superb to SLT as wasn’t totally happy since dealer carried out emissions update. The improvement in performance was immediately noticeable with more power but also how smooth it comes through. Fast efficient friendly service and a good guy to boot 😀. One very happy customer!- Derek Renshaw from sheffield 05/11/2017
I contacted SLT Remapping and Diagnostic LTD to see about a stage 1 ECU remap. I read up about it but was a little skeptical as I was always taught, "If it's too good to be true, it probably is."
After a long think, I decided to take the plunge. Mark came out to my place of work and was done in no more than an hour. I took it for a quick spin and the difference was immediately obvious. The throttle response became sharp and meaningful, the low down torque that you get from a Diesel engine seemed to be spread across the rev range and the power was significantly improved. The car even sounds better and more refined. I'll not get bored of the extra 40+ BHP and definitely not the 80NM of torque. 10/10. Would 100% recommend their services.
A very, very happy customer.- Lee from Sheffield 18/08/2017
I was put on to Shaun of SLT Remapping as I had a major fault with Jaguar XF. I had back to the main garage I purchased from and they only made the car worse Shaun took my car and sorted it out yes it took two weeks but I have to say this gentleman said to me this car has big issues but it won't beat me I'll have it running like new well all I can say is I picked the car up Saturday 5th and it' drives like a dream all I can say about Shaun of SLT absolutely spot on and amazing what this gent does to sort your car out I would recommend SLT to all my friends and colleagues this gentleman is class and very good at what he does so if you have car problems look no further than SLT Remapping of Sheffield.

After having nothing but trouble with the egr valve on my Audi i booked in SLT for there egr solution with a stage 1 remap after been quoted £500 to replace the egr valve.
I must say the service was second to none and the extra power from the remap makes my audi much more fun to drive!
