Muzzy's and MSD at high altitude

Anyone have any experience running dual Muzzy exhaust and the MSD controller at altitudes from 7,000 to 10,000 feet on a 700.
I realize the fuel injection and the computer should take care of this but before I make the investment I want to make sure it works.
Thanks.

No, don't. However, it should work fine with one exception. You will need to utrn the key off and back on when at high altitude so the ECU can read the barometric pressure. If you drive it from lower elevation to high elevation without turning the engine off, it will still think you are at the original elevation.
As long as it is mapped well for your current conditions, it should work fine at any elevation.

Thanks s2k1, ya it spends all summer parked at 7,000 feet and we ride out from there so I guess the ECU would figure out where it was.
