I never looked under your hood but I thought the old owner put a newer turbo on it. Its either a cooled H1C or a HX35. Take a look at the tag on the turbo, I may have it confused with another rig. I agree with KTA. 400 is not the easiest power to break. It takes bigger amounts of cool air. Your turbo is stock ( just not sure which one ) and you have no intercooler. If your going to work the truck leave the power low or you will have it busted. All high power does on a work truck is break everything behind it. Thats my opinion and others may not agree.
