Well actually in my eyes, my car has always been on the low side when it comes to making power . I was dissapointed with my first dyno run..248RWHP with alot of boltons. And after the cams I wasnt too happy with my 274 # and was ok with my 292RWHP # but still expected more. Same when the turbos when on...I actually expected a bit more than 479RWHP @ 9.2PSI. Now this time around making 498RWHP @ 8.5-8.7PSI, I was pretty happy and felt my car was making the #s it should be at that PSI .
