My 05 only has Ramair intake & TORs pipes with a tune.
Last year rode 810 miles to Stearns, Ky.
500 some odd miles in the twisty hills while there. The 810 back.
Cruising at 75-80 @ 3000 rpm on the interstates all I could think about was man this girl eats road. Had a couple of @sshats blow by me on their H-Ds & all I did was turn the screws a little bit to blow right back by them

Gearing never crossed my mind as I didn’t even have to shift

You need to quit worrying about gearing and just derestrict the ole girl
