Ok this is the problem. I noticed the other day that my secondary boost wasn't coming online like it used to. It had been a while since I had used it so needless to say I was purturbed. What happens it that at transition secondary boost seems to build real slow and is finally at a full 10 psi around 5700 rpm or maybe 6000. When it reaches this point it begins to flutter from 10 to 8 and continues to do this until I let off.

I was thinking that it may be either my precontrol or wastegate solenoid. I can't seem to find any vacuum hoses that have come off. What is the sentiment of the experts out there on my case. Thanks for anything you can give me.

 

I have heard that people with hawk brake pads generally have these symptoms...

 

Wow if I only was able to put that together before I wrote this post. I mean I must be braking so hard that it is boiling my fluid and therefore superheating the air in the engine bay. This in turn makes all the solenoids fail because of the extreme conditions.

But really does anybody have any idea.

 

I was having a similar problem. All I did to fix it was replace my check valve going to the pressure tank from the turbos. Hopefully that gives you some help .....

 

I'll have to check that check valve this weekend. Does anybody have anything else I should check in the mean time?
