I think he's stated he is running a 28" rear tire. I love my mt82, I can shift it a whole lot better than my old 3650 on it's best day. None of the weird lockouts and crap people complain about. And, regardless of the gearing in the trans, and if it's going to be useless in 1st gear...isn't any supercharged mustang, regardless of the transmission...useless in 1st gear. I do most of my playing around from 2nd gear on up anyway. Start out in 2nd most of the time, or go 1-3-5-6 in town. Doesn't bog, or have a hard time taking it. I think it is geared perfectly..my 3.31's feel perfect, I wouldn't want 3.73's unless I ran a tall tire to offset it some.
I say go for it, you seem to always be able to be in rpm regardless of speed. Not like my old 3v, where you had to slow down, or speed up, to get it to a sweet spot where it would feel punchy.
