Please dont rip me but i couldnt find anything when i searched. I keep reading that giac is better that apr in a 2000 a4 1.8tqm. Nut i was just wondering how much boost would i be running with an apr or a giac, how many psi. Thanks in advance

 

i have a 2000 a4 1.8tqm with the apr 91, i spike around 17ish and settle around 14 -15 psi but when its just perfect ouside, i spike around 19 and settle at 17.

 

I have APR with a b5 audi, and i spike at 15.

I have heard the same, that GIAC is better then APR, and I believe it, but not to say that APR is bad or anyhting. I love the APR chip. The only reason I have heard that GIAC is better then APR is that it gives you more power in the low RPM's. The APR chip kicks in at around 3,400-4,000 rpms.

hope this helps

 

giac is more aggressive

b5's love giac
