Hello all,

Ive been using hp tuners for a little over a year now, and have recently ran into an issue with the new ford powerstrokes. There is no longer the gear/tire wizard tab in the drop box which is what I have been using in the past to make tire change adjustments. I tried going under the "speedometer" tab and manually adjusting the tire size there, but after making my changes the speedometer is still off by about 10-11mph. I changed "use tire circ." from "learn from BCM" to "Calibration", then tried adjusting the min/max values but still with no luck. Any help is appreciated!!
