Lq4 dies when given gas I have a lq4 with ported ls3 heads intake and a comps cam. I had the computer base tuned and it takes a little bit of cranking to start up. One started if I touch the accelerayor it dies until I let off. Any help would be appreciated .

Its drive by cable. Its out of a 2003 2500HD, its in a 70 Chevelle. PCM is from Jon at PSI Wiring, it was based tuned by a local tuner using build specs. I wouldnt know how to post my tune. I should mention it worked good a couple of weeks ago and the only thing I changed was instead of just sitting the MAF sensor in the intake (which was just a tube) I have cut a hole in the tube and glued in a mount for it. Pressure of regulator is 51 PSI.
