I picked you this info on a LT1 Face Book page.

"The firing order is hardwired in the LS PCM. The repin has to change the firing order, so don't try to look for changing the firing order in the tune (it's not in there). This goes for the coils and the fuel injectors. However, because the firing order is different for the LT, you'll need to change the cylinder to bank assignment. *This is important or the fuel trims will never work correctly."

Is this true? I'm not ready to tune yet but in a month or 2 I'll be ready.

I bought V2 and a ECM AFM1500 to do the tuning with.
