I just purchased it and put it on my truck and WOW! Big difference! No more 6th gear with the torque converter locked when only going 35 mph! A lot firmer shifting, no hunting around for gears! Money well spent!

Agreed! Most people appreciate the firmer, more consistent shifting, locking out of the torque converter and more linear spread of the shift points. Enjoy!

I have this OD tune as well and like it alot. However, as of late, I have heard some rumours that it raises the line pressure past the safe operating perameters of the tranny. Can anyone clarify this please. Thanks

Ya they raise it to 175psi from 160(stock)

Some guys put aftermarket pumps in and run 250psi with stock internals. So no it's not passed its safe potential.
