i just received a livernois tuner, installed the 91 tune for my 5.0, drove it down the road, and it shifted through all 6 gears in 20mph or less and would not downshift until i stopped.

has anyone heard of this issue??

i put the truck back to the stock tune for the time being.

no one??

First thought that pops in my head is it thinks you've got very short tires. What did you select for tire size?

BE25FX4

hey snow,

i'm running 34's on my truck. i couldn't figure out how to calibrate tire size. do you have the Livernois AIW MyCalibrator Tuner?

the truck didn't have any power. i think something is terribly wrong with the tune.

Suggest calling Livernois today and walk through what you've experienced.

I'm guessing it had to do with the strategy?

There was a calibration change needed for aftermarket tire size. The N/A tuners do not allow you to adjust tire size on your end like the Ecoboost F150 tuners do. Problem solved!

Perfect. Was just curious. I had seen a different strategy cause similar effects, so just wanted to know so that if someone experiences it I can help out is all.
