Has anyone else experienced wild MAP sensor readings that seem off at high rpm?
I've done a bunch of dynos and it seems my MAP goes from reading 100 down to the 30's which then causes my fuel to cut down drastically?
I've mitigated the problem by increasing fuel across 4800-6000rpm at low map readings but my fear is that I'm having a valve-sealing issue.
You can see on the green chart I sett the fueling higher at low reading and that smoothened out the power curve but it didn't fully get rid of the issue.
The spike at the end is because I thought the dyno operator was gonna cut off the reading so I fluttered the pedal a bit.
