but you all seem to think that it's just reading absurd numbers. you guys are coming off that instead of 421 i should be somewhere in the low 3's. when i hear someone say "way" or "real" high what am i suppose to interpret that as? yes i believe that it might be a "little" high. but at 17.5-18 psi i believe that it should be above 400whp. again, i have seen dynos where guys are putting down 380 on 15psi and i was almost 3 psi above that. yes i understand that there is detonation that occurs at certain rpm's that aren't audible. but simple fact is that i've been running this car at this boost levels since for a while now. and have done a some compression numbers and they have always come back good. so i'm not really worried.
