I have a 99 mustang with a vortec supercharger and a aftercooler system. I'm having problems running lean. I purchased a U7146 and have played with it quiet a bit. I've noticed that the spark advance and fuel adjustments are all WOT. Is there any adjustments I can make to get this thing in the normal range on my air/fuel gauge?

The Predator does not contain the necessary range of adjustment to tune for a supercharger. You need to visit one of our CMR dealers and have the car properly tuned on a dyno.
