After changing to an NW102 on my CTSV, there is this annoying hiccup after release the throttle. It wont do it from very light throttle. here's a pic of log when it happens.



The event happens at the white vertical line and lasts for about 1/4 sec. RMPs drop several hundred then pop right back. It's like she goes into open loop during the event.

Any help is appreciated...
