I brought the boost valve back all the way up with no change.

mov00008.mpg

See if this vid helps. Listen to it studder around 80mph. If you turn you're sound up, you can hear it studdering all the way through. Watch the tach at 3500 and 5000. It seems to stop for a sec.

Well, i'm leaving for my trip tomarrow. So maybe in one week/ 2500 miles later the PCM will have adjusted. I will not run at the track and i'll go easy as I don't want to damage anything.
