A tune should be the first thing you do. No need for a list of mods to tune. Tuned is tuned, regardless of mods. Just have them go ahead and turn off the o2s in case you decide to use an ORY or whatever, but besides that, the tune will be the same with or without bolt-ons. (Cam and heads tuning is different of course)
I ran 12.5 at 110 with a tune, lid, and cat-back (stock 3.23s).
