trying to help a friend out here.
he has a single turbo setup on a 4.8 truck version of the ls. it has a speed inc tu1 cam (225/225 .585/585 113lsa)
so while out driving, we've noticed around 2000 to 2400 rpm and the map value of 50 to 55 kpa, the car is rich and will just work it's way lean. the car has a th400 with a loose 3500 stall in it. i'm a beginner at this and we're both lost on where to start.
