Hello guys So i have an '99 S3 with CP Carillo 82.5mm 9,5:1(SC-7613), cat cams springs, ferrera exh/intake valves and Eagle H-rods. I also have a Standard K04, cheap china 3" DP. Cars got upgraded clutch also. Pretty much everything else is stock. My tuner is having issues with the car starting to knock when adding boost. Its running 0,7 bar that slowly peaks to 0,9 bar... So its not really fast. Its on 98 octane vpower fuel. Shouldnt this car be able to handle more boost, or is the 9,5:1 CR really bad for the K04 and now im stuck with a really expensive forged engine in a car that goes nearly as bad as it did stock.... Any advice on the matter would be good, is the tuner just bad or is my setup ****?
