Ok just got done with turbo install on 2006 silverado. Now since there were no COS for 2006 I took a 2005 OS 12592618 off holdens site to match the motor and trans. Full flashed it, and did the CO3 install. All went in great. Made all my changes and was getting ready to start tuning. Starts fine, take off down the street and give it some gas and it pops a U0107 code and falls into reduced power mode.. What would be causing this, has to be in the tune somewhere truck ran fine with the 06 OS.
Any ideas?
Current tune is attached..
