Re: 2004 H1 upgrades
Damn. Good luck. There are a few things you can do:
Marine injectors
Mechanical wastegate (bump up your boost)
exhaust
Here is where the problem begins. You have the CAT designed computer in your 04. 04 being the only year the CAT system was in the H1 I am not aware of any computer upgrades for your truck, which will limit what you can do besides the computer. Take bumping up the boost; you can do it, but only to a point. Depending on what CAT decided was the cap off for boost, you'll start throwing boost malfunction codes on your MIL light. It can also de-fuel your engine. The only performace mod that I would really look at if I were you would be an intercooler. Its expensive, but its TOTALLY safe. From there you could stand to sqweeze a bit more boost out of the turbo with the wastegate. FWIW, doing this will not bring you anywhere close to Alpha performance (just so you know). Good luck, I'd email Travis at Rubber duck 4x4. He sells performace parts and is a hell of a good guy to work with.
