[QUOTE="Mdub707, post: 32683, member: 107"] New "issue" popped up last week. The turbo vanes seem to be "shutting off" while I'm in drive crusing around. Doesn't ever really happen when I'm accelerating hard, just when I'm cruising around in my town (30mph limit, real slow driving), sometimes taking off from a stop sign, you can hear the exhaust pitch change and the truck gets throaty, I take off and it really wont spool. Same thing happens at cruising speeds with low RPM's. boost falls below 10 and then out of no where I can hear the truck lug a little and look and boost drops to almost 0 and sometimes right to 0. Doesn't seem like a sticking turbo since it will come back up and go back down quite easily. Maybe the VGT solenoid? Doesn't seem like a leak anywhere, it still makes ~33psi pulling hills in the race tune. I have also tried a few different tunes and it does it in all of them. Thoughts/comments/suggestions? Is there something I can monitor with AE to see what is happening? I don't personally have it, but could borrow it this weekend. Thanks. [/QUOTE]
