To fix the power enrichment, I returned the ECM 9692 table to stock. To correct the "Engine Ind Torque Limit", I added 20% to the ECM 44779 table. I tried increasing the 2 bottom rows of the Driver Demand table, but it did nothing for the boost or throttle limiters and caused the "Engine Ind Torque Limit" again. So I lowered the 2 bottom rows of the Driver Demand by 10% to correct the "Engine Ind Torque Limit".
Attached is the last tune & log from today. Thanks for the help.
