Thank you for your reply. The truck is pretty tough and moderatly fast. I agree with you on the turbo limiting my perfrmance. Would an S300 be to small? Found one for 800

I think an S300 would be a good choice.

Quick spool up?

a s300 ought to light pretty quick with how much fuel ur runing BUT its all in the tuning to get it to light quickly.. if the pumps not tuned u could be dumpin too much fuel at the wrong time which means it will get laggy n egts will go up

You're not gonna be happy with the S300 and that much fuel, you'll be running HOT. I had 370's, 191's, a 0 plate, and some pump mods... With all that fuel I was turning an HX55 turbo, so a tiny (in comparison) S300 isn't gonna cut it.

no but an s300 with the 64mm comp inducer will, even with the 62mm comp wheel. An hx55 has a 2.5inch or 63.5mm inducer, with relatively old technology and a big exhaust housing (usually 17,19 or 22cm). There are a lot of companies that will modify an s300 for you, or you can just go find an s366. You can get one new for $1050 from AGP turbo. But that comes with a similarly large housing being a t4 inlet with a .91 A/R, but it has a 76mm ex. inducer. It will take a little while longer to spool, but will provide enough air/exhaust flow to burn the fuel and really bring EGT's down as well. Thats just my opinion.

Thanks ill be looking into that.
