Hey Guys,

I have a 2010 Chevrolet Tahoe PPV with a 5.3L LMG and a 6L80 Trans (MYC) looking to drop in a 6.2L L9H. As far as I understand it is a direct swap. Would I run in to any issues or codes as far as the L9H not having AFM/DOD? I plan on using the 5.3L PCM and having it re flashed to work with the 6.2

Or do I look for a L94 that has FlexFuel, VVT, AFM like the LMG does?

 

Either way you go, you'll have to get the computer tuned for the new larger displacement engine.

 

L9h should have vvt unless you delete it.
