My mods are:
TSP headers 1-7/8 inch
Rotofab Intake (dry filter)
Mishimoto catch can
Flex Fuel Sensor (at the time of tune I had 58% ethanol)

This is a sure sign it's false knock. If you have access to the tune, you can go back and do three things:
- Turn off COT Protection (if you don't have cats)
- Increase knock sensor sensitivity threshold (mine are at 5)
- Lean your PE AFR's (target 12.8-13 for gas, 8.5 for E85)
Otherwise, find a new tuner who can do this for you...
