That's what I was trying to say, that I CAN"T tell the difference. That looks like a pretty good tach/volt meter for the money, I'll have to get one.

Bill the new radio I got will do the throttle curve set-up, but I gotta do alot of reading first to learn how to drive this radio. I think for now I will do as you suggest & just barely raise it above idle. I just gotta hear the thing! I'll make sure I keep it nice & fat & stay off the throttle, until I can get this radio figured out. Thanks guys.
