I see how you were toe to toe. I raced an 05 5.9 tonight in stock form in a 98 Nissan frontier 4 banger 5 speed. Dang cummins didn't have a chance. it was funny I thought but I was prolly turning 7k rpms before I shifted. Still it was pretty sad
AFC only controls how much fuel is injected based on boost level, messing with them shouldn't net anymore power than stock, only just put more fuel in down low....right?
Dodge- Expensive shipping crate for the cummins.
