2003 ford f250 super duty 6 l diesel i have stock 265 75 16 on truck now and i am putting 285 75 16 on ford dealer says it should come in and get speedo and tranny calibrated ,dealer said speedo will be out and that somtimes the tranny light might come on and shift weird and to bring it in to them and they will callibrate it for 60.00 i was wondering if our programers can just do it instead of takinf it in ? any input on this would be great thanks

No, at this time the Predator cannot recalibrate the speedo in the 6.0 diesels.

Thanks

Can it re calibrate for the 7.3 liter?

The latest revision for the U7170 will allow you to adjust tire size as it relates to the shift pattern, but it does not recalibrate the speedo....
