Hello forum I'm new to HP Tuners so bear with me I'm an old guy that just LS swapped my 64 Chevelle with a stock 04 5.3 with a ls1 intake and a 4l80e ,I have a PSI harness and they sent me a tuned computer ,it started up and drove but had no power and I noticed my exhaust pipes from the manifold were turning the color of titanium they were getting so hot so I assumed it was running lean ,I looked at the injector data and it was way off so I looked up the injector number and copy pasted injector data from a 02 ls1 Camaro I found on the sample page of HP tuner it ran a little better so i installed a wideband and its still lean. It sounds like it has a miss when listening to the tailpipes but I have no misfires ,knock sensor or spark retard data Im not sure if this harness has enough wires going to the OBD2 port or I have something not configured right .The OBD2 port only has 4 wires #2,4,5 and 16
Thanks for any help 64 chevelle 10-16.hpl64 chevelle MAP final.hpt
