HAHA, yer funny! Good bait, though, gonna catch a lot of fish with this one. See, everyone likes something different, and every sled is a little different, especially M sleds, for reasons no one has ever explained very well to me. No one "best". 77-7800 rpm is a good target on a stock sled.
I run a mostly stock '05 M7 at 0-6000'...it has a D&D y-pipe, a hacked fuel pressure regulator (running about 42 psi), and a 290 mainjet in the fuel line, efi controller reflashed to '06 specs. I run stock weights for altitude (75g.), with the AC gold spring for low engagement, a straight 38deg. dalton helix, and a goodwin dark blue spring (which you cannot get anymore
), but is so close to the AC orange that it probably doesn't matter, preload near zero, and a shift assist in the secondary. It engages easy, pulls hard to 6000', backshifts yesterday, and doesn't fade. May not be the "best", but I run it all year, all conditions, all altitudes, stock 036 belt, which I'll probably change this year, just for good measure.
Good luck,
John
