Default turbo 5.3L swap, which PCM?

I'm swapping an 04' 5.3L out of an Avalanche into a Lexus, should I get the computer out of the Avalanche or look for a computer out of a GTO, F-Body, Vette, etc? Will be using an LS6 intake, 80lb injectors, MAP tune, etc.

They are all more or less the same you just need to decide if you are goin DBW or DBC throttle body and more importantly what pcm you use is also determined by what year make and model of harness you are using on the engine.

Probably go aftermarket harness for a cleaner install. Would it matter then beyond DBW or DBC?
