Hope you get it figured out, Cal. I’m running NT05 on stock.

Yeah, that's what I'm thinking. With that tall 1st gear there's no torque when it hooks @ low RPM. Should get more pull on the low-end as long as I've got the meat to keep the extra energy under control. I just noticed that Hoosier P335/30R18 is like 2" shorter and has the 12" tread width to control it. I might even have to shift to 5th gear in the 1/4 mile with that one.
Since it's an eLSD it has to already have some kind of bias built-in. I'm not sure if all the stability control logic is in the ECM or some other control module. I don't think the M6 has a TCM. The eLSD control box sits behind a cross-member just rear of the diff itself but I don't know if it can be accessed directly. Be nice to know if it can be tuned.
