So apparently i have a vacuum leak my boost gauge is reading only 11 vac. It has been like this for a while now, it hasn't effected my MPG's enough for me to notice atleast. My long term fuel trim reads only 16.4 at its highest on my aeroforce. I tried spraying carb cleaner around and had no luck, no cracked vac lines, and i dont hear anything. No check engine lights are on or anything. The only thing I could think of is because of the bad LIM gasket, could this be causing this? I know for sure my LIM gasket is bad and needs to be replaced, I was trying to hold out on changing it until I finished my engine build but thats not happening anytime soon. So either way im gonna change it. Do you think that could be it? Im not to sure on this one, after I change the LIM gasket im gonna put new vacuum lines on and see what happens. I know average vacuum is around 17-18 or so.
