Superlift Truspeed sensor

[kanton1]

Is anybody using the Superlift Truspeed sensor to recalibrate for other than stock tire sizes?

 

I talked to Hypertech yesterday and they will not be able to offer tire size or gear ratio changes for the 8100 or Allison. The tech said GM has not released any codes for these functions.

The Service Manager at my Dealership is a friend and the best he could do was to reprogram for 265's, which is closer than the 245's. I'm running 285's now. I'll find out the speedo diff this week-end.
