Boost gauge reading -10 at idle
Having idle issues. I did a boost leak test and found a line off of the intake manifold. Put that back on and it still idles at -10, and now when I boost leak test it, it holds the pressure fine. When im driving and just let my foot off the gas itll drop to -22, but as soon as I push the clutch in it goes back to -10, and same at a complete stop.
Any ideas?

Only mods are intake, evo 9 turbo, exhaust, and apexi boost controller. No cams. And it was at -20 before. It sounds like it has cams, but it never did before. Maybe someone swapped me out some cams last night

It has already been tuned. Was tuned by the previous owner when he put the 9 turbo on. And now it just randomly stalled at a stoplight. Its definitely different than it used to be, I know for a fact it idled at -20 if not lower and now its at -10 if im lucky. Any chance it's the IAC valve?

A low idle will show lowered vacuum. the gauge didn't go bad at the same time the idle dropped. Check the vacuum lines, intercooler piping, etc. suddenly running funky, lowered idle, lower than normal vacuum, clear signs of a boost/vac leak.

Yes, gauge reads 0. Ill do another boost leak test. It held pressure fine when I checked it yesterday, much better than my z which has no idle issues.
Ill update with results then, Thanks

I forgot I didn't update this thread. It ended up being a bad tensioner which made it jump two teeth. I ended up just doing the full 120k mile kit. It's back to normal now. The timing belt took a lot longer than I thought it would to replace though lol. Much longer than any other I've done.
Thanks for the help guys!
