I just got my HP Tuner and want to get started asap. I have a 2002 Chevy changed the 4.8L for a 5.3L, JBL shorty headers, 160 degree term/stat, true dual with fatory cats and all 4 O2s, Magna/Super Charger(3.25 pully). I checked the Repository and did not find any thig close to my set up to get a base line tune. Wold there be any place I can down load a base-line to start wit?
