B8.5 A4 Stock/APR Boost Pressure
I was wondering if any of you knew the actual stock Boost pressure for a B8.5 A4?
I have a P3 Vent Gauge that I installed after I did the APR stage 2 and it is reading 28 PSI at lower rpm, and it gradually comes down to about 16 psi near redline in a 4th gear pull. Even as a boost spike, 28PSI seems way to high, so I am thinking that there may be some signal massaging errors along the way? IDK, any input would be greatly appreciated on what stock on these cars should run and if anyone knows the boost pressure of an APR stage 2. Logs would possibly return a coffee as well haha
