Thought I'd pick the brain of the MA collective: Two weeks ago I spent a couple of days on the track at Summit Point, WV. The main circuit has a 2,900 foot straight that's spent mostly at wide open throttle. After a couple of hard laps I'd get a CEL with code P0108 which is MAP sensor. I'm running a stock R53 head and injectors with a 15% reduction pulley, Alta intake, and custom tune. If it's like my old car before I upgraded to larger capacity injectors, it's probably starting to lean out when the injectors are run at or near capacity. I don't have an A/F sensor. But does that sound like a likely cause of the code? I tried testing the theory by clearing the code and running a session at a slower top speed (video), then went back to full speed the next session and threw the code again. Thoughts?
