This.
If you donít like how the truck runs, your pretty much stuck because the Aisin canít be tuned. I live at high altitude and the dead pedal and slowness drives me nuts but there is not much I can seem to do about it. Tried with a emissions in tact tune from calibrated power and it only made more top end power and nothing to improve response and low end. 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.[/QUOTE

There is a snake oil box out there that does pretty much resolve the dead pedal, I run one and it has helped out immensely with my Aisin trans on my DRW 3500.
