c8sup Posted September 30, 2007 Share Posted September 30, 2007 on the first turbo the gauge reads 0.5, then when the second turbo kicks in the boost stays the same. This should be 0.8-0.9 on a standard TT. Any suggestions to why this is? A friend did notice one of the boost hoses is blocked off, could this be the reason, maybe a leek? any ideas would be great as im losing alot of power, will try and get a pic of the hose:) Link to comment Share on other sites More sharing options...
Steviekid Posted September 30, 2007 Share Posted September 30, 2007 A friend did notice one of the boost hoses is blocked off, could this be the reason, Yes. Probably either the IACV or EGCV mechanisms. See here Link to comment Share on other sites More sharing options...
