I have a 6.0L out of a 2005 Yukon in m y1995 impala SS. I'm using corvette O2 sensors( faster switching), street and performance headers, and a homemade intake. The harness and PCM I have is from a 5.3L. Does the PCM need to be reprogrammed for the 6.0, or is there like a seperate table already loaded for the 6.0?

 

The PCM will need to be programed for the 6.0L
Data such as clyinder size, injector size, VE and all will be different.

 

exaclty what Trever said,it is very easy to do also.

 

Where can I find a stock tune or one that has been modified w/removal of the rear O2s and associated codes deleted, EVAP, and tuned for a cable driven throttle body for a 2005 6.0L? I'm planning on purchasing LS1edit and tweaking a few things.
