Dan Kyle maps are max power maps and relatively rich accordingly.
I tried it at a track day, and found it smooth to use, but I'm not good enough to tell whether it gave me any time per lap or not. I could feel/sense the difference, but that's all I can claim.
They are not the best for street, nor cruising, nor touring.
IF you are using DK maps, I suggest the following group of maps to try out :
919LBSato-DK-MW1 (a Lord Duck Hunter map)
919LBSato-DK-MW2 (a Lord Duck Hunter map)
919LBSato-DK-MW3 (a Lord Duck Hunter map)
While you at it, also try:
mw919mori4 (a Lord Duck Hunter map)
You'll also find that many of the maps in the McRomo44 Compilation folder have had extra Notes added to them. Also look for the A/Fs which if appear are just above the Fuel Table. Many of the map names are quite intuitive, pretty much all of the custom maps have been renamed to make them reasonably intuitive.
