I'd say I might have a spare ECU if you're driving through Reno but mine does something similar, mostly doesn't do anything exciting under boost and occasionally bucks on me. I've learned to work the clutch to limit the bucking. Figured I'd look into it again if it did it after the new engine's put in with the RobTune. Hopefully it stops with the new setup, driving to Tahoe from Reno is getting annoying in my car.

I think that might be something else. Im also am having a problem with my AWD. Im thinking its my duty c solenoid. The percentage of my tire spin is being weird. It causes the car to loose torque. At the same time it could also be my bad ECU.
