Anyone with 35s running the Ford Performance Tune?
I currently have a 6 inch BDS lift with 35s and used the Rough County speedometer calibration tool (which actually had to be set to 33.5" to get an accurate reading). I would like to run the Ford Performance Tune, but on their website it says "Tire size configurable up to a maximum diameter equivalent to a 265/70/17 tire"...

Is that accurate? If so, does anyone know if I would be able to run the tune in conjunction with the Rough Country speedometer calibration?
