Hi, My S3 (which I have only recently bought) has a Jabba custom remap to 290bhp and 320 lb/ft with in car adjustable map (dial to adjust from standard to max) but I seem to have a slight miss (a blip at around 5 - 6k) on full boost setting. Anything other than full boost setting is fine.... I am assuming that this is being caused by the amount of boost that it is running when on full? When I bought it it needed a turbo and I have fitted a CR supplied K04 with upgraded bearings etc. the previous owner told me it always pulled cleanly when he had it (pre new turbo). I would like to know what is causing the problem, as I say it is fine on any setting other than full... My initial thoughts are that it may be due to the fact that the new turbo is generating more boost than it was mapped for previously and the ECU is cutting in for safety? Or, it could be something completely different... coil packs??? I have heard about intake pipes collapsing in on high boost et. etc. It's a little concerning as I obviously don't want to damage anything... so I would appreciate any thoughts... Cheers!
