Just had my GTP dynoed today, not what I expected. 215whp/235torque. I thought I would be much higher at least 240hp to the wheels. Something is not right the car has gotten much slower this past six months. Its like driving with the supercharger belt off even though it is obviously not, the dyno setup measured 10.4 psi of boost. Has anyone ever encountered this with no codes and no KR with a "tuned by scan tune" on the car. BTW:My mods:WizAired CAI,3.5"Pulley,NGK-TR6,1.8 RR,3"DP,3"Cat&3"Exhaust.Custom PCM Tune.
