I agree more is gained by changing out the exhaust than adding the additional boost.

I hope you have a fueling strategies as the stock system will not support that level of power.

Playing with some numbers just for fun: A stock 3.6T is 360hp, remove cat/muffler = 380hp. Add boost, 380/1.8 x 2= 422hp. Convert to rwhp, 422 x .85 for drive train loss = 360 rwhp.

Most dynos read differently than the Porsche factory numbers. For example my chipped, cat delete 3.2 pulls 217rwhp which would be 255fwhp.

My maxed C2T with larger IC core, big ports, big exaust, euro head, SC cams... and the K27-7200 pulled about 330 rwhp and would only get to about .92 bar boost. I did not dyno it with the K29 or HF/7006.

380rwhp is 447 fwhp. Very impressive.
