Ok I have had my truck now for about 6 months. I have 2500 miles on it and have run the Edge juice/att combo since the first week of having it. I have just sent it off to get the Hot tune and I was wondering how it will work on my truck. I have a 6 speed with straight 4" exhaust and AFE stage 2 on it. I dynoed it the end of Dec and I got 422/770. That was level 5 and winter fuel. It has never slipped the clutch yet and I am running 315 so I was kind of worried how much this truck will take. Sorry first post.
