Do you have a DSP5 switch? Who did your tunes?
Relentless Diesel in Willis. Just north of Houston. Owner is an Aggie. If I remember correctly, his name is Chris.
No switch. Only a single tune. I asked him about it. He can do a multi program with switch but does not recommend it. He explained something about how the Alison Trans is programmed to learn driving habits as well as stiffen and loosen shift points automatically over time with wear.
It was his opinion that constantly changing your power outputs and shift points is terrible for the transmission.
