What customers say

Amazing difference on my VW Touareg after having the Gearbox Mapping done, to compliment the engine Map i had done. These guys are always efficient and know their stuff!. Highly recommended!
Lee Rundle VW
Great job tuning our BMW and Touareg! Had both engine and gearbox stage 1 done on both. The gearbox tune made a big difference i must say! Good booking process and efficient with time. Highly recommended!
Lee Rundle BMW
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…
