I'm fairly new to all of this. Is it just the aggressiveness of the tune/boost psi that determines peak hp/torque?
I just got my 2011 STI tuned yesterday (with AEM CAI and Cobb DP/Accessport, stock everything else) and am at 289 hp/325 torque @ 17 psi. I did ask for a conservative tune and maximum drivability. Are these normal numbers? I thought so but when I see WRX tunes like this it makes me wonder.
