MV dropping

I thought I would post this here in this thread as well...maybe related ??

I loose boost almost as if I let off the throttle. this video is third gear. while accelerating part throttle, as the acceleration is plateauing but speed is not ready for 4'th gear the boost drops and flutters. the car builds and holds boost normally under all other conditions. maybe just my driving style? i would say the knock gauge is responding to the "flutter."

Why don't you get a Powerlogger and monitor your O2s with a wide band? Much more accurate and you can learn much more by reviewing logs.
