boost gauge ?

well i finished the turbo install this evening and heres the problem. I know that the car isnt going to run worth a shit because i had to hack the downpipe so that i could install it. Im taking it to the muffler shop monday morning to get the rest of the it welded back together. So there obviously is no O2 sensor in the system right now, and of course because of this its throwing a cel 41 (O2 sensor) and running in limp mode. however my boost gauge with the car sitting at idle is around 20 vacuum. while driving normal on the way home it was around the same. i got on it a bit on the way home so i could hear the turbo spool and it did but i didnt read any boost. the gauge went from 20 vac. to 0 as soon as i stepped on it, but never read above zero. anyone know why?

You might have a leak on your piping system. Check and recheck. Or could be your wastegate.

yeah it doesnt feel like its boosting whatsoever

and if im hearing the turbo spool up like crazy could the wastegate still be the culprit

haha im an idiot one of my IC piping couplers had popped off. put it back on and its runnin like a champ now.

howd it run open DP?

eehhhhh so so i guess. ill let yall know how its really running when my injectors and ecu come in from xenocron
