I'm at 460 rwhp (on a Mustang Dyno), no issues to speak of at 16,000mi.
I did have a tuning issue after the install, but it worked out ok after Procharger tweaked it some more. I had an early auto kit and the tuner shipped with a 5spd tune.

I'm at 503rwhp and 520rwtq with a '05 Gt vert. auto I have a Whipple and it is making close to 11psi of boost. I've made 30+ passes with my current tune and have had no issues. My best 1/8 is 7.57 and best 1/4 is 12.08. I need to add a high octane tune because there is a serious lag when it shifts from 3rd to 4th.

edit: I have all stock internals

I put a Whipple (8psi) on my auto '06 GT just over a year ago, and I've had no issues thus far with my tranny. I have stock internals, and the transmission has a PI triple plate torque converter and a deeper tranny pan. So far, everything has held up very well, though I will admit I don't beat on my car that much, though it is a daily driver.
