hi, i have a greedy pro spec 2 boost controller set at 1.8 bar, which is high boost and 1.2 bar for low boost, but the car doesnt go beyond 1.2 bar even in high boost mode, everything was ok when i parked the car after 2 weeks i started it up went for a drive and noticed it wasnt goin to 1.8 bar, even if i change the settings on my boost controller the car doesnt go beyond 1.2 bar....

i have already checked for boost leaks, there wasnt any...

what could be the problem?

is the boost controller solenoid failed or what?

need your help...

 

i took out the boost controller solenoid and some water came out of it, is it damaged?

how do i check if the boost controller solenoid is working or not?

and also could it be a stuck wastegate that causing my car not to reach desired boost?

 

i took out the wastegate, inspected it everything was fine, so wastegate is out of the question...
and please guys help me out, i got 60 views and no replies, whats up?

 

i think if its boosting still to exactly 1.2bar then theres something wrong electronically with the boost controller thats not allowing the second setting .. maybe take it to a shop ? sorry cant be of much help

 

It's probably the boost solenoid, I would try and swap it with someone you know, that has one or of you can cash out the money for a new but I think is pricey around $100.

 

Try a different solenoid

 

Where are you sourcing the boost reference from? Is it from the compressor discharge tube nipple, or is it "T"eed into the intake manifold/BOV hose?

 

You could try running a mbc To see if be boost will go higher. You'd know if it was he solenoid or not after that.

 

Mine did that on Sunday,exactly all of the above.We tried swoping the boost controller,checking the waste gate,disconnecting the boost gauge and even the dump valve....nothing.

So on Monday morning after I had a boost leak test done my car started smoking heavily.So it all started making sense,the turbo is stuffed! At least in my case...

It has been losing power and also been hearing a rattling noise,so I think it's the turbo exhaust impeller scraping on the inside of the casing.
