Assuming the tranny is ready and everything else work the way it should are big EFI Live tune safe for my duramax.

How big?

I'm assuming from your other post that you're looking for a 135 hp tune? That would be just fine for a truck with a built trans and enough air in and out.

With built tranny & a liftpump 500hp is doable.

500 can be doable without the lift pump in some cases
