2008 6.4 u7164 tuner

[robbydiesel]

i just purchased a diablo predator u7164 for my 08 f-250 and it works great. i can tell you that it the best programmer for the money. power is unreal. on the 80 horse program it will haze the tires from a slow roll. on the 160 program it wiil spin as long as you hold in it. very fast. gas mileage on the 80 program picked up 4 miles to the gallon.
the only thing i see that it doesnt have as advertised is the adjustable shift features. when you select this feature it says the vehicle/trans combonation does not support this. is this right? it does have tire size, gear ratio adjustments and top speed.
also, shift patterns are great and not to hard, even on the extreme tune. thanks.

You have a updated Transmission calibration thats why it says that its not supported. The next revision which we are working on will support the new transmission calibration thats in your truck.
