Re: Which MSD rev limit chip to use?
Now that I think of it, the motor is probably done AT OR NEAR 5,500, but if it has some to go, and your really pushing it, just for fun or if it decides to make power at 5,500, the 6k shouldn't hurt anything.
go with the 5,500 or 6k, always good to have a little more rpm past the power band if you want/need it.
Say my motor made power at 6,500, i'd install a 7k chip.
what ever you decide to go with, it's much better if your not paying attention or miss a shift and the motor spikes to dangerous rpms (it happens fast)
