Sam's tunes are normally spot on at wide open throttle with the air / fuel numbers. 450whp is conservative, but not all gas is created equal. Running too much timing on a canned tune could turn fatal if the tuner isn't able to watch all that is going on.

Where are your numbers around? 11.1 - 11.5 a/f at wide open?
