Im just trying to get the truck where it will move in and out under its own power. I feel like i am just overlooking something. I switched the tune to a 3-bar speed density tune but now its hard to start and when it does finally fire up its dumping a crazy ammount of fuel and dies. Truck has a 76mm heads and cam 6.0 with manual valve 4l80e. It has a zr1 map sensor. If anybody could shed some light on this it would be greatly appreciated!
ecu is 2002 silverado v8
This is my first time posting here, i usually find what i need to by searching but I would like to have another set of eyes on it.
