Can a complete lbz tune be full flashed in an 06 truck that currently has a lly tune file? I am trying to avoid working with the stock operating system and or lly tables,but i am unsure if a different os will cause troubles
The LLY and LBZ in 06 could both have teh same OS in them, but the engine segment will be different. Yes you can find a stock LBZ tune file and full flash it in and go.
