Hello
Im a new f6 owner and I've got a dyno tunes 2012 f6 with 379 rwkw , it is hunitng for power at top end, could this be a coil breaking down? , or is it an injector thing ?, or valve ? fuel pump delivery?
I am unsure of any of the modes to car ,
believed it was to be stock with remap tune, but unsure,
as the tune shop had no records to what they had done other than the dyno sheet. any suggestions to why ?
thanks in advance
