Let me know if you have had any issues. I think we have basically the same motor and electronics as FOMOCO treated Lincoln and Mercury as bastards when it came to performance.

Well My car has been down and out with my tremec swap.... long story short pieced together everything with new and used parts and A+B dont equal C so for 3 weeks its been sitting at my buddies shop with us only getting a few hours one day a week to put it on his rack. I rebuilt the fmu so should now be fine on the top end with fuel, also calibrated it to the 30lb injectors. Your setup should be similar to mine, i guess you still have e7 heads tho, you need to put a check valve to your MAP sensor and a small bleed hole after the check valve in the hose to vent any boost that gets through. MAP sensors do not like positive pressure. My motor was the exact same as the speed density mustang hipo. Not sure if the xr7 was the hipo, but with the intake changes and such not much difference. Im guessing your paxton is the 1220... the 5-6lb unit will be more friendly. Actually with the 30lb injectors in mine... it doesnt start going lean till a few lbs into boost when the fmu wasnt functioing
