Thanks guys, the hypertech is an option, and Dave gave me a good price, but a local shop that has a very good reputation and actually does some work for the dealers and was recommended by some fellow ram owners can do the speedo calibration and install the tires for less than $80.00. That savings can be added to suspension upgrades or deletes down the road. Really appreciate everyone's advise and thanks Dave for the fast response earlier. I will definitely be giving you a call when it is time to do the deletes.
As far as scanning for DTC, I can already do that with my tablet with a Bluetooth adapter and the torque App. Not bad for $20 for the app and adapter, now if I could get it to work as a programer as well that would be great. No wires to run and one less screen to look at. Keep hoping H&S or someone will come out with a replacement touch screen radio that does the programming, or at least compatible with my tablet.
