I looked into this myself last year. American Powertain has a cryogenic gear treatment that increases the torque capacity of the TKX from 600 lb/ft to 985 lb/ft for $1065.

They offer the same cryogenic treatment for the T56 magnum as well. That torque capacity goes up to around 1100 lb/ft IIRC.

Having two overdrives would be nice but it’s honestly kind of unnecessary unless you are doing 1/2 mile roll racing events. I am still leaning towards the cryo T56 magnum for the extra torque capacity since I will eventually be running a large single turbo setup.
