Accuracy of Kleeman power claims?

also, they have to retune my ECU twice to get that number, 1st time it only make about 50whp and my transmission cut out once it hit redline.
btw, the 381whp is with the resonator removed and X-pipe installed. Baseline was 302hp everything is stock. So you ask if the number is what Kleemann claim..what do you think?
