STICKY VALVE causing 2nd boost problem??
 
well, I notice whenever I turn on just my front orange light (like the corvettes) for like 30 mins driving, then when I punch it first boost is fine and then 2nd boost just lag. It was 10-7-5 all the way.. WTF. And when it's hot, 2nd boost dont' come in at all. Is it because of the two selnoid connector in front of my pressure chamber going bad. Or just vac. probs.

It can't be vac. probs. I check and all the vac. lines are still good.

Any thoughts and ideas are appreciated.

I've had sticking actuator valve problems before. Charge control actuator was sticking open really bad every time the 2nd turbo hit. It's inside the y-pipe

Try that.

so it can't be my two selnoid connector that is under the pressure chamber.??

look at pictures.

It's the two connector can only see it when the pressure chamber is off.

so hes saying he has boost problems only when his "front orange light" is on? that is a bit odd.

i had this problem for a long time, and never got it licked. i figured out that it was a heat problem with one of the solenoids. and i replaced 4 of them, not sure which ones now, but i would look at my airtemps on my commander and as soon as it got around 55degrees my secondary wouldn't come back on, pattern of 12-6-5. so i would go through winter with no problems, and as soon as it started getting warmer and air temps started rising (since its a good indication of heat soak and underhood temp) i started getting the same problem again. like i said, i replaced 4 solenoids trying to fix that, (and other problems) and never figured it out. now i'm single, streetport, ect. so i dont have to worry about it. but my buddy has the problem too. so if you figure it out, let us know :)
