Get the cp swapped asap. Its a ticking time bomb even on stock boost. Also need fmic if running anything over stock boost.

Ditch the racechip. Get a proper flash tune like mhd or bm3.

Your bolt ons will then let you run stage 2 tunes. That should get you to around 390-400whp.

Will need a stage 2 turbo to hit 450hp at the wheels. Most popular is Pure Stage 2. You will be mid 400s on pump gas with ps2. Low/mid 500s with fueling upgrade.

I recommend reading up on ghassan before buying. I've read a fair amount of negative stuff about them.
