[QUOTE="Jeff@Spartan, post: 460828, member: 223"] I'm sure it was a high reading dyno or a really high correction factor. Remember, my truck made 637 on Rudy's Dynocom with stock fuel (other than ported fuel rails) and stock turbos. The next day it made 594 on David Dunbar's dyno. You guys know as well as I do that no dyno reads the same and a whole lot of them read really high. [/QUOTE]
