Is not STI. But yeah it had a small boost leak and it was fixed along with an installed boost restricter. It boosted well for a day or so and then it lost it's power. I had ran low octane for about 23 days and promptly changed to high. The mechanic reckoned the engine is fine and Im a bit lost that boost is down. Had it checked today for another leak and none found. This time they checked a code for a cam sensor - P0365. They found some oil on sensor and cleared the code. Test drived around the block and no engine light. I paid and took home but noticed it shunts slightly when cold and in low gear. but ok when warm. The engine is at around 243xxx Ks. Is 2001 bug eye. Sounds like the cam sensor needs replacing.
Cheers Scotty 👍
I would start by replacing the cam sensor like you said. That could fix it.
