Horse power Limits of 38mm Tial Wastegates?

New built motor is almost ready, just wondering if my 38mm Tial wastegate would cause me any problems? My goal is 350-400 WHP Stock sleeve Straight LS (Built bottom) Thanks...

I've seen 400hpa no problem with a Tial 38mm w/g... you should be fine!

A local here was making 540 SAE (like 430 uncorrected up here) on the older design Tial 35mm. I wouldn't see why you would need a 40mm+ wastegate unless you are using a full T4 turbo.
