boost controller problem

[white98gst]

aight i just installed a hillman boost controller. but when i tune it, no matter what my boost guage always says 10 PSI but it creeps to 11 then goes down to 10. sometimes it feels like alot more than 10 psi. is it my guage or the boost controller

where are you running the line from???? turbo outlet or the BOV line???? i did mine off the turbo directly and have had no issues....if its not that...something may be pinched such as a vac line for the guage or controller....

i T'ed it into the BOV and the other vacumme goes to the wastegate

what kind of bov do you have, remember the stocker leaks.

Bypass the mbc and go for a drive. Boost leak test if problem persists. If not, check your mbc set up.

Maybe your BoostController is backwards?
