I was out tuning last week on one of the cold nights. Car was very fast and running great (23ish psi). I started doing a bunch of 5th gear pulls to make sure I had no knock when all of a sudden the car felt slow, I looked at the boost gauge and it was showing 10-11 psi at WOT. I did another pull same thing. I drove it home did a boost leak test, found a minor leak, fixed it. Also wound up having to do an axle seal when I noticed that there was tranny fluid leaking from the drivers axle. Finished that up today, put everything back together and took her for a spin. Same thing. I then took a capped off vacuum line that I use to cap off the j-pipe nipple when boost leak testing and put it on the j-pipe and disconnected the boost controller. Did a quick 3rd gear pull went right past 25 psi in a split second. I know have the boost controller in my room. I took it apart cleaned it out, cleaned the ball+spring, and put it back together. When applying air to it it seems to be acting normal. If I put this back on and the car still doesn't work right, what else should I look for?
 
Nevermind... after cleaning the boost controller and reassembling it I was able to reset boost to what it was again.. Car is fine. :dsm: :)
