Nice numbers. I need to get a new intake. I finally got a new T/B and new catback. Then I will get a new tune to see what kind of numbers I can get.

After installing the intake, you should make more power than my car, seeing as you have a monster cam. I am predicting you will make 380 to 400 at the wheels. With my cam, I will prolly need some P&P Z06 heads to get over the 400 mark.
