Thread: performance shift

The hand held tuners like Hypertech won't help you much. You need someone with a DHP PT to help you out. Give me a few minutes and I'll post the two tables at are different on a car with performance shift. Please note that even though there are only two tables changed on a stock PCM when you flip the switch, with a Tuner there are a few more rables that have the Normal and Performance Shift tables you can adjust.

If you have a tuner, some additional Normal and Performance Shift tables
