Ive got the giac 4 program chip in my 2000 1.8t and im only hitting about 14 psi. I forgot to ask the PO of the car what he had it set at. Im guessing its on the 91 considering that 14 sounds pretty low for a chip. Also sometimes when i floor it ill be building boost probly till about 10 or 11 psi then it will drop till 5 psi and stay like that till i restart the car. Im guessing either bad MAF, N75, or a boost leak.
This has really been pissin me off. Someone help me out here

Actually have another question thats completly off topic but needs to be answered. I'm looking at a set of wheels. They are 18X9 with an offset of 44. The dude at tire rack said they arnt gona clear my (stock) brakes. I was wondering if I could throw some spacers on there to clear them or will that poke out the wheels and look stupid since there 9 inches wide.
