I have a 2004 1500hd lq4 with 100 shot of nitrous I sled pull with wanted someone to take a look at the log and tune i have see why its pulling timing? Maybe just knocking and I need to run less timing? I only run this tune when sled pulling. motor is bone stock runs on 93 and has a wet shot hooked to the fuel rail
Thanks PULL TUNE.hpt lindsay.hpl
