Have yet to do an LS swap, but I'm a veteran of many late model engine swaps into older vehicles.

If you're doing an OBD2 swap of any kind you NEED a code scanner or a laptop with some means of reading fault codes, and wonder why a tuner would tell you otherwise.
I can't imagine tackling a swap flying blind.

Does your software guy have a known-good PCM to make sure the problem isn't your PCM (or his flash program)?
