Took my 96 GTS to the dyno to calibrate the VEC 1. Had little or no luck in doing so. Every time I ran a good dyno hp the next one would be all screwed up. When the car was WOT on the bad run, the A/F mixture meter would come off rich toward the lean side by two lights and I would lose power. The next time it stayed at the rich light and would have a great run. Something is going on. Car is modified with Cam, Headers, Heads, and Roller Rockers. Settings are -4 low side +4 high side. Can barely feel differance on the road but on the dyno you can see it. I had a viper tech install the VEC 1 this spring, not sure if he soldered the wires or just connected them. Was wondering if it may be bad connections or something with fuel. I am getting a 52 too rich code and a 42 a fuel pump relay control curcuit. Numbers on the dyno are 507rwhp 537 torque on the good runs. On the bad runs the numbers start going bad after 3500 rpms. Thanks for any help you can give
