Hi im New to this forum. Need some advice on performance upgrades. Been reading some forum write ups but need a little clarity to some upgrades that I had I mind. I just want a little more power nothing major. I rarely tow anything but have a heavy foot. Daily driven 40miles round trip to my job. I have 250k miles. I dont know about the about the injectors and balance rates but I know I that the previous owner bought a brand new Allison trans. Everything I have that I know is in my sig. Just replaced the hydrobooster seal, brakes , and front wheel hubs. Looking into tie rod sleeves and an down pipe and intake. But I'm confused on what kind of efi live or box tunes to get for what I want. Also how far can I upgrade for the things that I want. Been reading forums and seen parts that need upgrading. Ex. Lift pump, intake, tie rod sleeves, efi live tunes, exhaust, PPE boost valve, gauges, etc. Need a reputable company that has all these items as well as well as brands to purchase, or is amazon and eBay the way to go. Also my airdog lift pump just gave out.(air dog fp100). Do I also need to get a larger lift pump.? Going to give air dogg tec a call soon.Any help will be much appreciated. Oh I also live in hawaii, where parts and services are hard to come by. Thanks.
