My 2 step is set at 4,500rpm which is too high, I want it at about 3,000. How do I change it? I went in and there is a place called custom tune and when you click on that it goes to Fastlane custom 93 tune. I dont see anywhere to change the 2 step and I dont want to mess anything up.
Is it something I do on my computer or plugged into the car?
