i guess i'm failing to understand what's so HARD to believe that i got the numbers i did. you guys are making it sound like my car should put down 300 whp instead of the 421 that it did. evans car put down 405 or something of that sort on 15psi. i did 15 more wheel horsepower on 3 more lbs of boost. in my mind i don't find this hard to believe.
