OK , i have researched some ..not a professional tuner.. hopeful i have enough info to help guide me to resolve this issue..
Stock no mods beside the air intake from factory L96 6L90 from a 2017 express put in a 1971 3/4ton suburban. swapped to a E38 and PSI harnesses programmed the ECM and Transmission together.. have a corvette pedal..
I am getting a P0606 reason 22 code MCP reduced power when i am an higher RPMs. PSI said it was the Dorman throttle body , have replaced it with an AC delco gold blade still getting the code.. The wiring harness itself it a BP automotive harness and is new. It only does this at higher RPM or like when I try to pass someone.. I have read that all the operating systems need to be right to have it to function correctly..Do i need to update the OS to a Camaro OS.. have attached a log file.
Aslo resently took the truck on a 3500 mile trip and it only occurred twice but was cautious not to get into higher RPM range to not make it happen. Hopefully i have given enough info.. Thanks to all that can help
