Prior to me working on the car it would boost 10-14 on the primary and the secondary. Problem was after the transition it would not boost again till I got below 3,000 rpm.

Based on others that had similar issues I pulled it apart and replaced the two turbo control solenoids ( pressure/vacuum). I replaced them with new ones and when I reassembled the car the transition problem was gone but now the car will not boost to 10 on the primary. Now I get 8 & 10 psi.

I thought I might have had the waste gate, and preturbo connections backwards so I switched them but the problem got worse. It would only boost .6 in both the primaries and the secondary. Any ideas?

ps I have no boost controller so that can not be it.

 

I figured it out. My coupler was letting go.....
