Here is the preprogrammed information for the MSD 4245, as you can see, it really only has one ''performance'' tune on it.
MSD at 50 MPH, I'm referring to the tune limits. Tunes 1-7 are the same (performance), 0 and 9 are stock, 8 is their Chaperone tune.
I would think there could be some more to be gained from actually tuning it to my machine, but I am not a tuner, so going to leave well enough alone.
