Performance Shift
01 and later cars didn't have performance shift in them. Lots of people will find a shifter knob out of an earlier car and wire it back to the PCM. You have to change settings in the PCM so that the trans settings change when you turn the switch on. HPT doesn't support the function to add this and DHP does.
Someone will just say to adjust the normal settings to a performance style and be done with it. I don't like doing that in my car, there's a big difference between a "normal" shift pattern for city/every day use, and the "performance" setting where the shifts are higher, tighter, and tire chirping.
