Thanks for the replys guys. I used datamaster to log it last time. After driving it today the hesitation seems better, but still feels flat up to around 2500. I will post the logs later when I get home to let you guys see what you think. The plug wires, cap, and rotor are all new Accel brand. 43ts plugs are a little old. The only thing I'm not sure of is the module, it had a distributor put in it a year ago. Still puzzles me how it has no hesitation on the stock chip but does on the modified chip. It has no cat and no egr either. The 4th chip that is currently in here, seems a little less rich because it seemed to want to load up and sounded like it had a big cam in it on the 3rd chip. Thanks again for trying to help me out. Lord knows I need it!
