recently had my 03 A4 130PD superchipped to 169 bhp (fantastic performance well happy) However after havinga service the car feels like it did prior to the chipping. I have had the car tested it is stil chipped (no overwriting done) We tried a new MAF (no change) the diagnostics came up with aproblem in the engine support valve ??? would this cause the power loss.
Any help would be appreciated
