View Full Version : Quick question regarding GIAC chip

02-11-2008, 06:53 PM
As posted a little while ago I just had a GIAC chip installed in my A4, I have 112,xxx miles and my boost spikes around 22 psi, is there anything else that I must get to not damage my engine or turbo? is boosting up to 22 psi bad? should I not hammer down and boost that high? thanks in advance any input is appreciated.

1.5 bar is not normal. if that is the case you could have a dying N75 or something leaking causing your boost to overshoot. I have a 2000 with 179k and see 1.3 bar peak. my actual boost meets requested perfectly per my vagcom logs
