data logger and autotune
i am about to purchase a data logger from vtech. from what i have been reading, the autotune feature will adjust my fuel table to make ski run better/faster/safer correct ? will i need to get more parts such as a rrfpr or pump or any of that crap or will the autotune adjust to what i already have? besides an intercooler and maybe retainers i didnt want to go any further.

No the data logger doesn't tell you what to adjust. It gives you the proper data needed to make informed decisions on what to do with your engine to keep it safe. You need to know what you're doing to look at the info from the logger.

NightmareRXT-x-AS...if all you have done to ski is whats in your signature, just ride and don't worry (unless you are spinning over 8400rpm). If that is what you are running, the logger will only clean up your midrange (a little more mid pull). Provided you use the data logger properly.
Even when doing an "autotune" (vtech) you need to run the ski in a controlled and specific way. Ignore that and the data gets noisy (fuzzy). I only use autotune to get me close to the ball-park, then I use MLVHD software to study each cell (& hits) and make manual corrections. Then when things look safe at all RPM's I put away the logger and make a couple more minor (manual) changes to fuel till I'm happy with sound and butt dyno (always below 2%). I will never part with my data logger, but most of the time I look at what it tells me and rarely let it tell me what to do (hope that made sense).
Anyone looking to buy a data logger, you must buy MLVHD and consider that as part of the cost & process, I can't imagine manually tuning without it. The rest is up to the human - fail or succeed. If all that scares you, find a shop/tuner to take it to.

Imposter, Sanfish, where does one learn about tuning? I have v-tech and want to get the logger soon. How do I go about learning how to tune?

tuning is not fast or easy
its always better to be on the safe side than on the edge
you should be concerned about the vtech tunes
when a tune has more timing than the factory tune
you are getting closer to the edge you dont want to cross
there is always many variables that can change your tune day to day, so your tune may get closer to the edge
start with a stock tune and try to get the whole tune to be in the safe zone
when your tune is in the safe zone you have room for those variables
to move your tune closer to the edge and not over
