38 helix

I run a 38 helix on my m7, really like it on long pulls it upshifts harder and I gained more on the nitrious.
But not sure if it will do what your looking for. It does build a bit more belt temps in real deep snow. Light snow and setup snow its accelerates much harder and I see higher track speeds.

I, too, like the straight 38 on my stock M7 at 0-4500'. It does tach a little higher at slow speeds, probably not the best drag race or trail riding helix, but the best so far, for me, in deep climbing. I also agree with saber, makes good trackspeed. Running goodwin dark blue secondary (almost identical to AC orange).

I run a 42/36p by black diamond with an orange spring and a shift assist and really like it on an 07m8
