In fact it towed worse in the lower rpm range so I removed it and now have an expensive paperweight.

Drove a 19 Aisin and although the 3.73ís help, I am not convinced that it is enough of an improvement for me.
I have the Aisin and I am tuned. I also added the throttle sensitivity booster and the Aisin has been awesome. I run the 100 hp tune empty and 50 hp tune when towing and no issues in 5 years. Shifting is great. Glad the C&C come with the Aisin. The throttle sensitivity booster really gets rid of the dead pedal. Very touchy now. The TSB and EFI live really work well together.
