Does it require a tune?

[VTGT91]

So I'm about to complete my build for my 96 GT. Full PI Swap, and rebuild including the block being bored 0.020 over. I also am putting on a 78 mm BBK 1780 throttle body. Seems like the engine will be breathing a WHOLE lot more than it used to. Will the computer require a tune in order to run efficiently? Also if I did decide to get a tune, can they do anything to it other than advance the ignition timing, because with this setup I doubt i can do that anymore for fear of being octane starved. Thanks for the help.

Couldn't hurt to get a hand held tuner.

I don't recall guys needing a tune with the PI swap, and definitely not the throttle body. No reason to put those parts on without taking full advantage of them though (meaning yes on tune).
