I know this has been covered but i gotta share. I installed a beetle map for my v7ii approaching 30000 miles. The beautiful wife bought it as a anniversary present. Gotta say the difference was more than a little impressive.
First thing i noticed the idle was much improved.
The shifting felt smoother (i attribute this to smoother fueling )
The bike in every gear was smoother, no lurching in second like before.
Acceleration was improved.
I sustained speeds in lower gears that normally feel at the top end.
Very impressed.
To confirm i rode over to a friend's to have him try it. He noticed the difference right away.
Man wish i did this sooner.
