so I had a shop install the controller, set it at 10 and 14 psi, worked fine for about a week, then nope...now I have INFINITE boost lol. even with the controller off, its still over boosting. the shop cant get me in for weeks, what should I be looking at for whats wrong??n infinite boost make engine go boom if I am not careful!

Usually the wires going to the solenoid get damaged.

Carpetguy · 03-02-2018, 04:53 AM

Mine just stopped working too.Have to figure it out aswell

dreksnot · 03-02-2018, 08:36 AM

Also, check the boost reference lines into the wastegates. If they pop off then overboost will occur.

stevieturbo · 03-02-2018, 01:29 PM

Based on your description...it sounds like a pipe has come off the wastegate.

Although that should never be able to happen as naturally they'd all be secured properly and use good quality pipe....

dreksnot · 03-02-2018, 02:54 PM

Like so...

stevieturbo · 03-02-2018, 02:56 PM

Exactly how it should not be lol.

I would agree with Kevin, this seems more electrical. I think if you just had a line off the wastegate it would resort to spring pressure. Having infinite boost tell me the controller solenoid is locked open somehow and you are at 100% duty cycle.

Nope. Losing a boost reference line will resort in max turbo boost. Been there, done that, fastened "correctly" now. Not going there again.

stevieturbo · 03-02-2018, 05:20 PM

There is almost nothing electrical that will give the symptoms he is describing.

The most obvious place to look is as per above.

caper · 03-02-2018, 06:05 PM

thank you for the advice, and particularly the pic! I didn't install it so wouldn't be sure what to look for. guess its time to crawl under there.

AGP Turbo · 03-02-2018, 08:06 PM

Oh right. Anything bad in the solenoid would result in spring pressure. Overboosting is a bottom line or diaphragm problem. A little hole in a diaphragm can cost you thousands guys. Be careful
