I need to upload some logs. I took a quick one while driving. I don't think it's the tune. I'm going clean MAF etc to see if anything there could be the issue.

If its speed density tuned then the MAF shouldn't matter

I thought you said you were speed density tuned? Why bother with the MAF if that is the case. You are way off.

Mine used to do this, it would idle around 900 and then just shut off, usually when coming to stops. I had an AP at the time and raised my idle by 300 and it solved the issue, but later found out the MAF needed a cleaning. That said, call your tuner

Contacting Doug would be the last step for now i'm not convinced that it's the tune yet. Checking the piping, couplers, and any vac leaks.

I have a log but i'm not sure how to post it.

My guess is an intake leak, small one at that. If you can't find one, you may want to do the compression and leakdown tests. If all that is good, then bother your tuner.

I'm thinking that too. It's probably a leak somewhere. I hear a hollow sound breifly if I tap/rev the motor to 1500-1700k

yes its the blowoff valve indeed, not the waste gate. Good point. It was an AP I think.

Have you checked for boost leaks yet or if any vacuum lines popped off any sensors?
