Thanks for all the responses. As far as recirculating the BOV, I have tried it with the BOV disconnected alltogether, no change. I ended up crushing the BOV just to be sure. I am using the stock 04 BOV, not the plastic Bosch valve. And as far as richening up the cold start rpm, I have added voltage to the anti stall maps in the 900-1400 rpm range. It just dosn't work! It will idle fine, as if normal for the first 10- 20 seconds, then it wil drop vacuum some and die.

Kevin, didnt you end up lengthining the pipe between MAF and turbo? How did that work out?

Thanks for all the help!
