Dyno after: PCMforless LS1 fans, Vector CAI/HSRK, Corsa Touring catback. It had roughly 800 miles on the odometer and the motor was thoroughly heat soaked for this pull. It was a warm (~80º), muggy, rainy day. I did not get the second sheet with the weather or correction factor so it is a rough guess. I am a bit disappointed with the gains, but then again my baseline was a lot higher than most ever are so this end result is probably more realistic.
