I was having massive power issues and lots of black smoke, but it got pretty much all cleared when I blocked the EGR and fitted the dawes and catch can. I'm not sure what my boost was before all of that though as I got the gauge done at the same time. I just know now I'm not having the massive power lose i was having before, which wouldn't let me get above 80km/h. Now I can get up to speed I just can't keep boost. power still isn't great though.
