Car was not getting proper boost. 5th Gear pulls. My current mods are CPe Nano Intake, Forge BPV, and Hypertech tuner. The Car was also hot, first pull was 174 AWHP. Something isn't right...my boost goes to 16-17 PSI for about 500 RPM until 4,000....where it drops to 13 PSI and at 5,000 it drops...
