Apparently you have been using the site's search "feature" which, IMNSHO, sucks. Go to any of the major search engines and add "site:the370z.com" to your search string. This will limit results to the site given and produce much better results.

The rule of thumb is: if only intake mods or only exhaust mods are made, the ECM can adjust itself; if intake and exhaust mods are made, you should get a tune. As stated above, your AFRs may be off.

Any good tuner can remap the throttle response in the ECM which will do even better than the SprintBooster as the tune eliminates some of the delay in the ECM.

Your tuner should be able to handle that with no problem. You can even get switchable maps for different octanes and other factors.

Then a remote tune should suit you just fine. You only need a dyno tune to eke out the last few HPs.

I haven't had any dealing with either one, but they both get great reviews on this site.

Cost?

I don't know. See preceding paragraph.

Going by what I've read on this site, it is very noticeable and I don't remember reading about anyone that didn't think it was worth it. As per above, you
need the tune because of your mods.
Edit: Don't worry so much about the HP/TQ numbers. All the reports I've read from people that had their cars tuned (even those that got remote tunes) say that the car is more enjoyable to drive. And that's what it's all about.
