I have found John and his team great to deal with!
I have been using Performance and Economy remapped files from JF Automotive for the last 18 months. My customers are always satisfied with the improvements to their vehicles after remapping. I have found John and his team great to deal with. Not only do they provide quality files but are also very helpful with any questions or technical support.
We always find the files excellent with a fast response
We use JF Automotive files as part of their dealer network. We always find the files excellent with a fast response rate and customer back up. Also when customers ask about the files we are more than happy to point to their website as a fast and easy reference
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!
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.
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.
