    guess no1 cares to bother since its a 4.8.... anyway update! got the truck tuned tonight. runs good. got it updated for the cam and t56. all the dash lights went away and the truck runs awesome. i need gears badly! thing wouldnt idle any lower than 1200rpms. guess im gonna have to live with it. (because of how large the cam is in reference to how small of cubic inches i have). also tuner told me hes buying a dyno mid april so hopefully by may ill have numbers by then as well
