Car is 05 STi, installed Invidia bellmouth DP and N1 catback and the car was flashed to AP stage 2. However I only make ~15 psi in 4th gear and barely 16 in 5th. Shouldn't I be at 17 or maybe a bit more?
Unrelated, I did a datalog and my knock correction was 5-6 until 4,000 when it went down to 1. Then around 4500 it climbed back up to 5-7. Is this a knock event I should be wary of?
