08 silverado transplant

hello all
Curious to see if anyone has seen this. E38 ECU powering a 6.0L/4L70e(trailblazer ss powertrain) in a '70s older car with '08 Silverado operating system. The 6.0L has a Magnuson SC on it now and it will propagate "TQ management advance" (which I am to assume is -timing effective) and pull base advance way to low and kill power as I crowd into the throttle to WOT. I'm not sure how to defeat this and have tried raising/maxing various tables to no avail. The last few dyno short pulls it showed in upwards of 9 degrees of TQ mgmt. "advance". Raising my min spark with reference to TQ mgmt. seem to only give it that number as a target; as in commanding base spark under WOT airflows to 15* and having min TQ mgmt. spark at twenty it goes right to 20*
Not sure if I explained this reasonably but looking for assistance in defeating any input of -spark in reference to TQ mgmt.
Right now I am just working off of MAF making sure everything works
Thanks

I'm not at my computer right now, but add the Spark Torque Management Source PID to the scanner and log it.

Small hiatus but back at it. Thanks for suggestion; am I to assume you are referring to “Spark TqMgt Type” ? that indicates “Trans” when “Torque Mgt Advance” is present. If there is another PID with your exact description I can't seem to find it.

That's the one. TCM is requesting a reduction for some reason. I have a request in with HPT to investigate similar things but they have no eta.
