Hey. I need a little help. I was on dyno last week and made few runs. My boost was 1.6 bar and dyno shows 472 HP. After one of runs, we made decision to cool car a little so we turned off the engine and wait a while. When we turned on it again my boost was only 1.0 bar at redline and nothing more.
I've checked everything: wastegate, dv, turbo, leaks and found nothing.
I have no idea what's happened. It looks for me lit's something with boost steering. Is it possible without a reason?

Is it possible that my Grimmspeed after 3 monts is dead?

 

Up! I need help still, but...

I've logged wg duty cycle and it shows the values as are in rom, so it seems to be ok. After unplugged wastegate line, boost is going up, but I am having a feeling that it is not natural work of it. It seems like something is disturbing to spool iit n right way.

So... where should I search:

intake or exhaust leaks?
engine compression? (not much gases?)

My setup is lookin that:




EDIT: problem deleted

 

Maybe that info will be helpful for someone, who wants to buy Grimmspeed 3-port BCS.
First look and first days of using makes me really happy. When I had my problems with boost, I was search about 2 weeks - I've checked everything, even my all exhasut system.

The problem was in my Grimmspeed BCS. Someone, who preparing it to sell had to leave some teflon (I think - that was some white pieces) pieces inside. I suppose, that this pieces they're using to seal the threads... I've cleaned it and was better with boost.

 

good to hear you fixed the issue.
