Does it matter if I have an Autometer gauge cluster in my car? I used the Diablosport Predator to change my gear ratio to 4.10 and then installed the tune. It said the tune was installed, but when I went for a drive the speedometer was still off. What gives?
I'm not exactly sure. I read that book like twelve times and it does not seem very helpful. I used the basic HP tune and changed the gear ratio before I installed it. I thought that is what I was supposed to do. Correct me if I'm wrong...
