Crate LS7
I've have mine running for 7 months as a daily driver with zero issues. I have dynoed it and raced it at the track without any issues....my experience has been 100% positive! I'm just beginning the modifications to it now.

I'm going to try an upgraded TAC Module tomorrow. 98blackSS, did you use the LS7 TB and did you have any 1516 problems? Thanks for any help.

Are you using the OEM PCM? What tuning software?

Just needed to increase the table values for TPS Sensor Calc airflow (In HPt, Engine Diagnostics-General-TPS sensor-Calculated airflow vs. TPS vs. RPM). I just did a quick 50% increase on all values to avoid triggering REP.

Looks like it's basically checking commanded vs. actual blade position.
Perhaps setup your scanner to log ETC desired position vs ETC actual(TPS)? Shouldn't even need to start the car. Pull your intake hose off and have someone watch the TB blade. Make sure it operates smoothly from closed to full open while someone operates the pedal.
