What peice does the DP connect to? Is it a replacable part if broken? If it were broken would this result in an O2 sensor engine light? I am unable to boost my second turbo, which peice, if broken, would cause this? :wtf: TIA
do you hear any difference at all when the second turbo is supposed to kick in? if not, there could be a problem with your vsv's. if you can hear the egcv open up though and you are not building boost off the second turbo, it could be seized.
