I'm wondering if anyone else is experiencing knock in a similar area as I am. I am not going lean under throttle application either. Interesting thing is that I datalogged before and after adding some race gas and the knock is similar in strength and in position in the map. The knock I'm experiencing is in cell P9-P11 N05-N06. I have one of those knock sensors that will read in 130 when drivetrain knocks around after releasing throttle. I'm wondering if this is drivetrain knock. Anyone with something similar.

Difinitely some type of noise. Check for exhaust hitting the frame or something scraping.
