Hello, I am new to the tuning here and am wondering what i need to change for an aftermarket cam and top end fueling. The truck doesnt like to idle or coast slowly. And it leans out above 5000 rpm. I have 42 lb/hr injectors and 10 lbs of boost. Am i running out of injector? Or is there other tables i can change?
