Make absolutely sure that the fuel injection on your engine is set up correctly. They've switched to a different controller after the problems with the Accel system, but you really need to take it to some high altitude place (like 10000' - go to southern Colorado over Wolf Creek Pass) to see if it will run. The problem is Roush is at 700' and they don't do very good high altitude testing or compensation.
