This summer I have a few things I'd like to do to my truck before I head back to school. I plan on upgrading my clutch and i'm looking at the velair clutches. The I want to get an arsen kit to help my rail. I'm not really sure what to get so I need some help my truck will backfire sometimes and somebody said thats my problem. I also want to stack a tst on my smarty and get my injectors extruded. What else do I need to do to support what I want to do? I do plan on upgrading my turbo also. Will an arsen kit take care of my rail pressure and are they hard to install?
