Fantastic service by JF Automotive.

Customer support always immediate and thorough. Had a stage 1 remap with Remus catback exhaust on my BMW 440i. Iain went through all the steps concisely. Results were phenomenal. Have had a few cars done but never have I noticed such a change. Not only did I get on average 22% extra power and torque throughout the range but it feels more urgent. At low speeds and cruising the car feels no different, but when the pedal is down it absolutely goes. Will only come back here now in the future! Thanks again guys!

It pulls earlier and harder in higher gears

Many thanks guys for sorting my Golf GTI
The results are very impressive. Acceleration is now very strong and the car is much quicker. It pulls earlier and harder in higher gears making gear changes less frequent. I am very pleased with the results. As far as mpg is concerned I have yet to do a long trip to compare but initially it's very similar to how it was before. I'm expecting better mpg on long cruises. On a recent gentle run 55mpg was indicated. Very impressed. Thanks again.

The torque that really grabs

Just a quick thanks to all the guys at JFA. Had my brand new F-Type remapped having seen Jag bring out a '400' version of the same engine (and add a few thousand £'s to the price tag). The power increase is impressive with 415bhp (from 375), but it's the torque that really grabs you as soon as you get back in the car. The power is so much more usable and instant!! Thanks guys.

My 2011 Lamborghini had both a TCU and ECU remap and it's totally transformed the car along with BMC Carbon filters as recommended. Total professional setup and very knowledgeable people.. I would definitely use again.

These are the boys to talk to!

I had my VW T5 mapped by the chaps and what a difference in performance now. It's a different vehicle. The lads at JFAutomotive really know their stuff and very professional and look after me, they kept me informed with all that they were doing. If your looking for a remap on your vehicle then these are the boys to talk to. I highly recommend them..
Thanks Mike great job.
