I've got a 16GTPP, and swapped out the factory 3.73 pumpkin and stock axles for a 3.31 pumpkin and Ford Racing axles. I've tried Forscan and a Whipple flare to change the ratio in the BCM. In either case, once I change the ratio in the BCM to 3.31 I get a U0422 error that I can't clear. If I change the ratio back to the 3.73 the error goes away.
Regardless of the setting in the BCM, the car falls on it's face unless you're barely on the throttle. I've seen many people talk about this problem before you change the ratio in the BCM, but never after. Anyone seen this before?
