I have wore out all efforts. I am going to start fresh as in another post i explained my issues with my tune. i am going to start off with my stock tune and modify it heres what i have, p59 ecm, lq4 stock bottom end g5x3 cam and supporting mods, rob jovasi 70mm turbo looking for 10 lbs of boost, walbro 400 in tank, c5 vette filter regulator. Maxed out the stock injectors so i plugged in a set of sd80's, used gregs data for the injectors car starts up great runs well but under 40kpa the car is rich as hell. I am convinced my injector data is wrong, I have ruled out mechanical issues due to putting in the stock injectors and the car runs beautifully but maxes out the injectors quick. I am looking for a spreadsheet to develop my own data and from all of my reading this is going to be a pita. Any useful advise is much appreciated thanks again.
