code 43 help before i waste money

[pearl91chevy]

I finally got around to logging the teal typhoon with datamaster.. I also just installed a TT 2bar chip. I started the truck and right off the bat its throwing a code 43 and my knock retard is a solid 7.0, and occasionally bouncing down to 4.4 for a split second.. stays the same during driving and all.. no check engine light on or anything.. is this signs of a bad knock sensor??

also would like to add at 70% throttle, 11.8 boost, my spark advance is 11.2 for reference

Do you have the chip you removed from the ECM intalled piggyback on the TT chip?
The TT chip uses the knock circuitry from the stock chip. If that is not installed you will see constant knock in datamaster.
