sd code 25 problem

[joel huttunen]

hey! i figured to ask here if anybody else has had this issue . i keep getting sd-code 25 at 100km/h when pushing fullthrottle and it cuts power , i know its upstream pressure code and have switched for new pressure sensor wich is in the front of the sled and i have switched for better hose clamps and recently also checked all the throtthle body connections aswell . running stage 4 tune atm . i cant seem to figure out the problem and any help would be very nice!

I had code 25 was very cold out boost tubes full of oil and moisture .
I took it all apart cleaned all the boost tubes boost cesors and lines.
Then vented crankcase to atmostphere and oil tank vented to atmostphere after the check valve .
Pluged of oil tank were it vented to intake. Works great no more codes and clean turbo and intake .

Finally the issue is solved , ended up going thru all kinds of stuff but the issue ended up being in the tune , so did , all tubes new , changing out pressure sensor etc . hopefully my season will start now!

I had seen a few tunes that had to be redone to cure this issue.
