What was the purpose of drilling out the chinese wastegate? I guess I've gotten used to my unmodified Tials.
A buddy of mine who runs the crappy local dyno has an 04 1500 quad cab and had a similar setup on a stroked 6.0 bottom end along with LS6 heads (which are factory on the aluminum L33 block that came stock in the truck). Full built internals he had the undermount turbo pushing 530 to the wheels but ditched the setup for a 75 shot because the truck was in boost while towing and he didn't want to spend the money to upgrade the fuel system, now is at 550whp with spray.
Fastest truck I've ever been in, if not in 4wd high it just spins the rears.
