So we did the vacuum test with the fancy smoke machine last night, found out my turbo has a very small leaking through the front cover on one particular section, possibly the o-ring that seals the cover. This tho, I don't think will cause my issue at idle. No other leaks anywhere what so ever. USED THE VACUUM FROM THE BRAKE BOOSTER TO DO VACUUM TEST

My tuner sent me this

"your manifold absolute pressure at a stable idle should be between .28 and .36 at most. Yours was around .5 or higher, with correspondingly high fuel trims. This indicates a leak. "
