Since it was tunes early this year it has been running fantastic. It has 24000 original Mike's and has been in the family it's entire life. I just drive it on the street as a weekend cruiser. I don't beat up on her, unless on the interstate and want to go fast.

I put it in the garage on the Tuesday before memorial day after an evening cruise and everything ran great. I went Tuesday, 5/28, to take her out for a drive and it was very hard to start. It has never been hard to start, not even a little. When it was compression tested in the spring the numbers were well in the green on both rotors. I got it running and it just wanted to fall on it's face. I got it on the road and slowly started to drive it. No primary boost at all, gauge reads vacuum at all times. If I get up to 4500, then I get full secondary boost.

I have been to the actuators on the turbos and the c clips are intact, and they are remaining closed as intended on start up.
I've done the beat visual inspection of the vacuum lines that I can. I went through it while it was running and revving it and also hear a loud scream out of the intake pipe while revving it by hand under the hood.

Before I start in taking off the UIM and going through testing the rats nest, is there anything else I should be looking into? Have I just friend a turbo?
