Got a Nelson tune. Lets start from the begining. My truck with a K&N CIA,Pacesetter shorty headders, stock Y-Pipe, 3 in. cat back with a cut out and Flowmaster 40 series , Diablo Sport tuner, Ran 15.70's at 86 m.p.h with a 2.40 60 ft. on 30 x 10.50 slicks at 4200 ft. of elevation.

I installed a GMPP LS1 hot cam with the same set up as listed above and dropped to a 16.28 at 87 m.p.h.. My 60 ft. was 2.70. I understand the loss of E.T. becouse my 60 is crap, becouse the cam does not make the low end the stock cam did.But it pulls better up top. The salution? A Nelson tune and a Yank 3000 stall.

I installed the new Nelson tune and nothing. It idels worse, it surges, has less low end , runs rich, revs and does not pull, and hold gears too long at cruising speeds. I have not installed the stall yet. When I ordered my tune, I told Nelson I was putting in a 3000 stall. Being I installed the tune with out the stall could this by why my truck runs so bad now? I am going to put in the stall on Saturday. I called Nelson up and they said I could send it back for a retune but I'm going to wait and see if the stall fixes it. What do you guys think?
