Absolutely! DCC1464 comes through and confirms Mike Litsch of Diablosport. This was exactly what I was asking for.

Lastly, I got an email reply from David Jirkovsky of SCT. He confirmed the 3.91 ratio is supported but not as a directly selectable parameter. David explained the adjustment comes through as a ratio of the stock factor. Below is the direct cut/paste of him explaining the setting:

Yes there will be support for that, but it wont be listed as 3.91, you will have to change it by percentage of increase. So whatever stock is, you would divide 3.91/(stock) and you will get a number 1.xx. That xx is your percentage increase. So if they are 3:45 stock, it would be 3.91/3.45 and that is 1.133333 so your percent increase is 13% and you would set the tuner to 113.

I followed up by asking if that is a USER selectable setting and not a custom tuner setting, and he confirmed it was USER.

So SCT WILL DO our 3.91's off-the-shelf, and without a custom tune at an added expense.

So I got a Intune and checked out the gear ratio setting. It is adjustable by 0.01 increments per push of the left or right arrows. I didn't check the upper and lower limits though.

By the way, I'm amazed with the off-the-shelf 91 octane tune. Smoother, cleaner idle, faster throttle response, and the power comes on like it should.

Just a bit of follow up for those keeping up with this. I finally installed the 3.91 diff a couple of days ago and set the speedo correction with the Diablosport InTune. I ran the car steady at various speeds from single digits up to 65+ and checked the speedo against a Garmin Nuvi GPS and they were identical.

As a sidebar, I installed BMR diff bushing BK029 and used Red Line gear oil (LSD additive not required) and I'm extremely happy with all of it.
