im in a local christian car club and one of my friends in the club just bought a supercharger for his 2002 1500. its 2wd, reg cab, and only has the 4.8. he says its not stock now but i know he just has ordered a hypertech programmer and the exhaust is quiet so he hasnt done much. i told him once he has it on and i get a few more bolt ons we will have to take em to the dyno and see who makes higher numbers and im sure a trip to the track would be in order also. im sure he will be running 8 psi at best because he wont have an intercooler. and by a few more bolt ons for me, i mean SCT, a big cam, e-fan, and an edge 2600 trq converter. i think i will hurt his feelings on the dyno
