my boost controller seems to read -18 to -19 lbs at idle and it doesn't boost right in any gear...doesn't anyone have any ideas as to why its not boosting right?

i heard it could be a pressure sensor problem, but i thought i'd get some opinions first

 

ok maybe this will help even better, why does my boost gauge read -18 to -19 lbs boost at idle? shouldn't it be around like 8-10?

 

I have this ebc but no engine yet so I can't tell you for sure but will letyou know who it works out for me.
