Wondering when you switch your DSP2 switch if your tranny has to go back into a re-learn mode. I have been getting some real ugly shifts that were no there before. The only difference is I have installed a DSP2 switch and have switched it back and forth several times. Truck will down shift hard and upshifting is crisp (harsh) to say the least. Wonder if this will be a problem with the DSP5 that will be coming out? Acts like when you set the PPE Hot 2 into re-learn mode.

If the base torque table and/or the torque limited injection quantity is different you can expect the tranny to act differently, too. Depending on how long you drive in one setting the tranny might adapt to the different conditions..
