probably around 270-280 ish, the thermostat, and MAF wont do anything for horsepower really. Just the headers, intake and cat back. Get a cam in that baby and you'll be well over 300

260-270, Then when when you need more power do a heads/cam combo.

Auto or manual? Manuals dyno higher due to less power loss through the tranny. Honestly though the car could dyno anywhere from 250-280 depending on how it is running. My friend's 95 dynoed 255rwhp with just a moroso cai. I put down 274/289 with the mods in sig.

Is your MAF a new stock piece or an aftermarket (such as Granatelli, Abaco, etc.) The combination of the Jet tune and an aftermarker MAF might not give the results that you are looking for. I would personally run the Jet tune and make sure I had a good working stock MAF.

As for your horsepower question, with a 6sp, K&N filter in the stock ram air box, HPP, Edelbrock shorties, SLP 2OTL exhaust, aluminum DS, and stock 10 bolt I dynoed 294 rwhp and 307 rwtq on a Dynapac dyno. Roughly 4 years later I had my motor refreshened (all stock. It was all I could afford at the time. ) After switching to a MAC catback it dynoed 297 rwhp and 341 rwtq on a Dynojet dyno. Assuming your car is in good running order you shouldn't have any problems duplicating my results.

heres a tip, when you get the granetelli mass throw it in the garbage asap. its nothing but crap and gives alot of people problems. the stock one is just fine and can handle more then 400hp

Agreed...also get rid of the Jet tune and get a real bolt-on tune from Madz29 or Pcmforless.
