Greddy Airinx Intake, Downpipe, Bleeder-T Valve, and Pulled Traction Control Fuse. From what I know these mods have been good for anywhere between 360 to 400 RWHP. It's hard to tell because the Bleeder-T Valve doesn't allow consistant boost levels. On a cold day I've read about boost levels around 1.4 bars (how many psi is that?) with this mod. I will be getting a Boost Controller and Boost Guage along with a TRD Exhaust which should allow consistant 400+ RWHP levels.
