Reviews

What customers say

Had my Audi S3 convertible remap plus gearbox remap the car drives absolutely brilliant
customer Audi
My VW T6 had a hybrid turbo installed and a myriad of other engine improvements such as intercooler upgrade along with charge cooler upgrades etc, the guys at JFA were great, setting it up was more awkward due to it not being a standard engine, but they tuned it superbly, 263bhp with the gearbox tweaked…
Ian VW
Excellent job by the lads at jf automotive, had engine tune/ gearbox service and tune on my x5, would highly recommend and would definitely use them again!
