Pretty good answer I'd say!

There is no real need to visit the dyno for a custom map. There are some decent maps available for most combinations of mods that get done to the XTs. The good thing is with a Power Commander is that you can try a map, and if you don't like it, you can easily try another. You should be able to find one "off the shelf" that pretty much suits what you want/need.

Having the map built on the dyno just enables you to fine tune it to suit you exact personal requirements (power, economy etc.) and also the subtle differences that exist from bike to bike. If you want a map that's 99% correct, then download one, if you want one that's 100% spot-on, then visit a dyno.

I'd always start with a downloaded map(s) to begin with and see how you get on. If nothing floats your boat, then book a dyno session. That's pretty much what I did in a nutshell.
