Went head with the 259e, putting the 500 miles before tune, looking at changing the changing to 30 front pulley, need to get more information, so many conflicting stories on the up grade,

 

taken the bike to The Dyno Difference in Dallas to get tuned on the 5/12/2012, exicited hearing good things about the Dyno difference.

 

You won't be disappointed. Ed is very thorough, takes as long as it takes to get it right. He tuned mine and it was well worth the 3 hour drive. I'm running 12/1 compression on 93 pump gas and have had no issues with pinging and I get 42-43 cruising on the highway.
