if you have any ideas and the time to help I would greatly appreciate it. Otherwise, no big deal.
in short, stage 2 custom os tuned, 2003 wrx 66,xxx miles. 2 years with the tune everything is good until a long day of auto-x, car feels sluggish. I logged and there is a lot of knock correction. its not particularly lean and the iam is fine, so I'm thinking vacuum leak. I also just got P1443 code which I've had before, not sure if the evap control stuff is related to the knock. any suggestions or ideas?
