Post Cobb Stage 2 HP

I just installed a catless up and down pipe, SPT cat back, GFB hybrid BOV, and i went one heat range colder on my spark plugs, then tuned with cobbs AP. I am estimating having around 300 crank HP. Does anyone know how to achive more then 300HP with cobbs stage 2? or would i need the VF34 turbo, and go stage 3?

Thanks.

Cobb gives the estimated CHP on their website(285).A custom tune,EQ headers and a bigger TMIC could get you 300 CHP without changing turbos.

The size of the exhaust wont matter for that power range, but like said its unlikely to get over 300 AWHP without the turbo upgrade. Like Dumdum said though, bigger IC and the headers, maybe injectors could get you where you want to be though.
