I believe having a dyno is a big timesaving convenience. The reading of my RT manual tells me that you can strap a computer onto the back of the bike and data log some runs (identical to making the various dyno pulls).
The graphs should give you a decent idea of what your fuel/air ratio is doing. Pushing it up or down in the RT is easy. Then another run on the street (sorry, I meant to say closed circuit track) can be logged to verify the results. That is how the tuner was setup to work, the instructions step you thru these procedures. You may need to try it a few time to gain a little experience.
The RT claims to have a limited range of adjustability to protect you from tuning it down (or up) to a truly dangerous level for the engine. If that's any consolation... That doesn't mean that over a long time of running too lean, you wont destroy your engine, because you can. It means that your next immediate run during testing won't endanger your engine
The RT certainly can provide you with the power and versatility to get your EFI dialed in very tightly. All of that should be possible without ever rolling your bike onto a dyno. Share your graphs on this forum and the V-Twin EFI forum and you will get some good advice from the people who have a depth of knowledge and experience tuning with the RT.
But you gotta make yourself comfortable that you can do this first. If you don't like your results, you can always flash back to your current baseline, and go find that far away dyno...
