Cruised around for a couple hours exhibiting all forms of driving. Started off with "mature adult" while it got to operating temp. That style was very pleasing as I could fully appreciate the low end pull under light throttle. Love the NW's C.D.P. harmony!

Then I stepped it up to "spirited" driving......equally enjoyable. So far no stumble. That was at lest an hour into my ride.

Finally, I went "Two Lane Blacktop" and received full satisfaction every time it slipped and spun at will! Overall a sweet sounding/performing XFire.

During this run of various moods I had the cutout/stumble happen just three times. Each time was far from the previous. Once cruising at 80mph while slight throttle depression. It was too quick to consider it a stumble, but it happened.

The other two were from a stop, into 2nd or 3rd with pedal going down slightly "spirited". That was it!!

Idle was smooth and precise. Cruising perfect. Full throttle at any speed resulted in loss of traction. (43* outside) It broke loose a lot with aggression.

All I did was "calibrate" before my drive. It appears to be 99% better.
