i think i am on a "race" valve.... the n75/map/and wastgate all come into play.... your w/g and n75 are the big factors there i think


but i am not a turbo guru so don't hold me accountable

 

do you know what wastegate spring is on the gt2871r? i believe its 1bar but im not too sure

 

i spoke to lavi over at Uni. he said my idle should be around 20-22, and since now im getting 14ish, he said i definately have a boost leak.

could a bad pressure regulator valve (Pancake valve) cause a boost leak? i took it off and i can blow air straight through both sides no problem, is this a sign that its bad?

 

check engine light came on again p0300 (multiple misfire) but this time it set my fuel system into an open circuit... so i believe this is soft limp mode??

are there certain things that could cause this?

 

bump.

 

Could it be possible that the 3bar FPR that i bought from usrt is not functioning properly? if so, is there a way i can test it?

 

It is right around 1 bar(14.5psi).


That is normal for the pancake valve. It closes when the vacuum on the turbo size becomes too high. You need to do a pressure test with the pancake valve blocked off or doing the pressure test starting at the turbo outlet hose. The leak is most likely something connected to the IM.

 

im planing on sending my ecu back on tuesday but i noticed that the car runs better with the o2 unplugged. it doesnt run as rich but is still rich and doesnt sputter like it did with the o2 plugged in.. the o2 worked fine before the mafless tune. does this tell me anything?
