What customers say

Had a gearbox remap on my T6 Volvo XC90. Shifts through the gears are now much smoother and I can def notice the difference in torque. Thanks folks.
Mr Christopher Mersom Volvo
These guys really know their stuff. I went there for a TCU gearbox upgrade which has made all the difference on my car, they were really competitively priced and helped advise me on a few other bits as well. I’m definitely going back there again for some more upgrades. I highly recommend these guys, not…
Darren
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!
