Yup just bolt ons and a tune. Mind you that was a small converter too.

Nice times sierracrew. I have a 2003 gms sierra ex cab 5.3 3.73 locking rear. I have the same mods that you do but I have long tubes and cutouts. I run 18inch rims. I can only run a 15.05-15.25. I imagine that the stall is helping you out. Thats the only thing I don't have. But I am at 2000 ft about sea level in kansas. Crappy weather too. 90+ degrees. Mine dynos 276hp and 318 rwtq. Later
