sudden loss in boost

[turbo970]

well up til yesterday my subie was boosting up to 10 psi where i had it set. then last night and this morning i'm lucky to get 8 psi. all my hoses and tubing are good clamps are tight. runs fine idles normal. just no more 10 psi. only thing i done different before the loss of boost was filling up at a out of town gas station. i have no engine lights. the gauge still reads the same on the vacuum side. could the vacuum actuator gone bad?

well i replaced the waste gate actuator with the one off my spare vf 11 i'll drive it in the morning to see if it fixed my issue

well my boost is back. i believe it was a touch of bad gas. i reset the ecu and bam my boost was back. i'll keep a eye on things.

I live in Oregon so I can't pump my own gas. The other day I cought the dude putting in regular, luckily it was only $2 worth.. I was pissed. I have to get out and make sure they do it right every time now. Glad you fixed your issue!
