I tested my AWD system again on the way home by putting my front wheels on gravel, while my rear wheels were on a concrete bridge - brought the revs up to 2000rpms and dropped the gas pedal. No tire spin and the car lunged forward smoothly.
Also, my CE light hasn't come on since plugging in the resistor and reseting the ECU - and I've done a few blasts to redline along with some slow idling city driving.
Knock-on-wood everything is good, but I realize it's too early to know for sure...
