I don't see the need for the 13 speed with the torque curve these engines have.
Heck, I don't even use all 10 of the ones I have all the time.
If you have a 10 c transmission you probably have a wider range of ratios than a 13 speed.
If you are shifting gears, you are not putting power down.
You might check the manufacturers website for ratios.
One would hate to go from an overdrive transmission to direct in high.
