I can't see a huge disparity between 100 performance and 100 race. I am going to assume that the race program is far more aggressive as far as accelerator pedal feel goes and probably has a much more positive torque converter clutch apply.
It's a good thing you're not worried about Fuel Sipper anymore since Power Hungry no longer offers that tune.
I would probably put in a tow tune such as 40 tow (as you indicated) just in case you ever do decide to tow anything.
