[QUOTE="Fred W, post: 1005854, member: 3828"] I have a 1st gen, and when I loaded the "Wally smoothness" map it did not resolve my surging either. I ended up getting another map from a forum member with an '05 that had previously paid to have his bike mapped on a dyno. That one was considerably richer in all of the appropriate fuel cell areas of the map, as could be seen in the DynoTune PCIII utility. My fuel mileage isn't the greatest, and I've been accused of having a somewhat rich smelling exhaust at times. But I do get 40-42 mpg (which is OK for the lower geared 1st gens) and the bike runs really well, so I have never gone the next step to get myself a custom map. I figure that a lot depends on the guy running the dyno, so a new map may or may not be better than what I have now. And while richer may be objectionable to some followers, it is a much safer place to be for the engine, as it will run cooler. Sorry we didn't get to talk before you ditched the PCIII, you may have been able to use it to meet your goals. But if you can deal with the surging, as many seem quite willing to do, the benefit of better fuel mileage is real and may be worth the minor aggravation. [/QUOTE]
