I wouldn't risk pushing the stock 5AT too much. I'm assuming your FI or will be shortly, the valve body upgrade is a must. I know someone who is pushing over 300whp with a stock tranny but don't know how long that will last.

With a VB upgrade you're good to ~400 WHP try to keep it under though! I had my Vortech at 387whp all day with no issues. Also supercharge only NO turbo.

good info in here about boosting an automatic:

general consensus is with a VB upgrade and big tranny cooler you should be fine up to 400 ft-lbs of torque.
