Hey everyone, Is there any way to change the shift data (re-program) on a '97' 2500 with the automatic? I just picked up this truck, and it has stock gearing with 315 75R16's (35 inch tires). The shift pattern is way off for the tires and I can only find stuff for years 98 1/2 and above. The truck has been modified as I understand it in the following ways only,

Edge stage 2 injectors
Edge Jammer turbo kit (put into a Holset housing)

 

You can change it somewhat by adjusting the tps
