2007 Avalanche 5.3 / 4l65e swap Ls3 Crate Engine from GMPP need Help for tune

[speedjunction]

Hello I was hoping to do a segment swap on Ls3. But i did not find anything with the OS.

How can I do it ???

thanks for help

You don't need to do a segment swap for the LS3. Just change the engine displacement, enter the new injector characterization data, then you can tune the VVE, or simply do a MAF tune.
