Well I'm new to the forum guys. Not new to lightnings but this is my first one. Not gonna ask a bunch of noob questions but anyways I'm buying a 2000 oxford white lightning Monday. Has 100k miles and is stock except bassani catback , a 2# upper , and a tune. Wa wondering what you guys recommend I do first. I was gonna change the oil/filter, put some tr6s in it, and order a jlp tune. I know tunes are essential for these trucks. Probably ditch the 2# upper and get a stock pulley . Want it to last as long as possible till I can save up for a built motor. What else do you guys recommend I do right off the bat.
