The other issue is our MAF's( Voltage will max out) Myself and Cliff ran into this issue but again that's if your looking 470ish . I had your Impeller upgrade and UPREV MAF's an was pushing 457WHP and the kit held up fine!! How ever on the other side of that was the sh&t install I had of the fuel pump.

I also had injectors and DW300 pump. I had the pump only cause the dealer killed the wally, and injectors were just incase I reached 500WHP, Which you wont see unless you have a built block.. Boost will be to high to get there on the the stocker, My 457WHP was at 11-12 PSI. You need like 16 to get to 500WHP.

To make 450WHP on your kit you would probably need nothing other than the front mount heat exchanger. ..
