SuperChip or ProCal and do it yourself as well as other mods you may want. Or go pay the dealer to do it, which in my mind is money wasted. Put that money towards somethnig you can own and use when you want like the above mentioned programmers.

if the dealer programs the speedo, will the shift points change?

I'm thinking the shift points are effected by the gear ratio settings.

The shift points should change when they set your new tire size in your computer which is what sets your speedo if I remember correctly.

Dealers can only change up to 33" tires. For 35's you have to buy a programmer and do it yourself.

Yes- correcting the computer for tire size will change the shift points accordingly.
