Trying to figure out why my truck seems low on power. Noticed my datalog is showing 10 degrees less timing than my BIN should be commanding. I matched up a bunch of samples to RPM and MAP in my tune tables and they're all 10 degrees less in the log.

I'm thinking it has to do with the code 43 I had that I turned off in the BIN. I checked the sensor ohms and the 5v at the wire and they were all good, so I turned it off. Does the computer still "see" something and retard timing?

9.7:1 Vortec TBI with LT1 roller cam (built and tuned in '11). Just checked cranking psi and they're all about 180.
