Always professional and nothing is too much trouble.

I’m currently running a JF Tune and GTS software updates on my F80 M3. My car has been transformed by both updates and well worth the money. Their approach and customer service is always professional and nothing is too much trouble.

Transformed my car!

The gearbox is so much more responsive since having the Stage 3 tune! Gearchanges are a lot faster, the car accelerates much quicker. By far my favourite bit is the full manual, with the paddle conversion its just so much better to drive!

Great experience at JFA, a very customer focused set up.

Great experience at JFA, a very customer focused set up. Iain took the time to explain everything at all stages of research and work being carried out. The quality of work is brilliant and i have every faith that the equipment supplied and fitment will stand the test of time. The car has surprised us all with the power it made but more important than the numbers are the delivery of the power and the torque is truly impressive, along with the stage 3 gearbox map the car is transformed. Did motorway miles today up to Surrey and back and car returned between 42 and 45mpg which is up from a regular 37 before meth and map. Barely any meth used as set the cruise control up to just before the 1.8k rpm start point so and only a few >25% throttle so from a mpg of both fuel and meth point of view I'm also happy.

Their knowledge and professionalism, is truly outstanding.

ASTONISHING! Having considered the possibility of giving my previous car a performance re-map, but never getting -round to it, I’m so pleased that I decided to do so on my Porsche Cayenne 3.0 TDI and even more pleased that I selected John and his team at J.F Automotive to do the work. Their knowledge and professionalism, is truly outstanding. I discussed the Performance improvements available with John, the MD at J F Automotive at some length and finally opted for a STAGE 1 PERFORMANCE REMAP – (up from 245BHP to 295BHP), Plus a GEARBOX TUNE to better handle the increased torque up from 550Nm to 636 Nm, give me increased shift response and increased red line performance. What a difference. Already a superb SUV with a great blend of sports car agility and pace, the PERFORMANCE REMAPPING and GEARBOX TUNING have completely transformed the driving experience. The torque spread is truly amazing, and the acceleration in sport mode - WOW! Just a tweak from my right foot smacks my back into the seat and brings a big smile to my face. You exceeded my best expectations Thank you Steve Sussex

Top class service from true experts in their field who actually care

Contacted these guys to Re-Map my gear box and engine on a new Mercedes E63s 4Matic AMG. What can I say…..Great service from day one and what a difference. I'm almost at 700bhp and 960nm of Torque!!!! The car is still very much drive-able and you can pootle along at 30 or rip your face off! I whole heartedly recommend these guys and they will even pick up and drop off your car if you are too busy.

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.

Great customer service

I went into JF Automotive just to have a chat about a remap and DSG remap on my golf R after talking to Lewis and him explaining everything in great detail about how they work and whats involved in the remap I had my car booked in for the following morning, Mike worked on my car on the rolling road along with John, I can't recommend JF Automotive enough great customer service and they really talk you through how it all works and keep you updated why they are working on the car with the power upgrades etc. My golf is up 65bhp and 132Nm tourque also im running a non-res milltek and the extra noises this produces now since the map is unreal, if you have a DSG box I would say get it remapped it improves it so much when you think it could never get better. Prices are very resonable for the results you get, If you are looking for a remap on your car head down to JF you will not be dissapointed. Thanks again guys.

Wouldn't go anywhere else

There are a number of tuners who offer similar products however it's the customer service and personal service that sets JF apart from the rest (as well as an amazing product of course) It's the 2nd car I've had tuned and wouldn't go anywhere else, I will always recommend them to friends and forum users. Thanks again John!!!

The torque spread is perfect

John and his team were very professional and extremely knowledgeable, and even came in early to accommodate my busy schedule. Needless to say the results are excellent and have transformed my car. The torque spread is perfect and the acceleration has changed from very impressive to manic!

Very surprised at the figures achieved

What can I say ……very surprised at the figures achieved by Mike, way over what I had optimistically hoped for. My 340i now has over 100hp more than stock and is now the truly heart stopping car that I hoped it would be from the start. Nice comfortable waiting area with coffee, biscuits and a viewing window so you can see what the noise is all about ! Would not hesitate to recommend JF Automotive to anyone looking to make their car more "interesting".
