Not always! When I boost mine up to 8-10 lbs, I some times blow off a vacuum line. Car runs fine but flutters when giving gas!!

Base on this "Basic Sitehttp://www.vortexbuicks-etc.com/basics.htm#IAC (Idle Air Control) Adjustment
Shouldn't the IAC numbers should be between 15-25; 50 is a bit too high

Between 10 and 30 is ideal but mine has always been between 40 and 50 without issue.

Vacuum leak would lower the IAC.

Well the spring in the wastegate was too stiff(15lb). I ran the vacuum line straight from the turbo port to the side port on the wastegate and now it holds boost right around 14,15psi. I ordered a new 8lb spring and hopefully that will fix the problem.

Thanks for everyones help

Congrats!!

Yea I didn't know that it being a 15lb spring meant that it only starts to open at 15psi and could make me run more than that. Learned something I didn't know lol
