Oh, and I forgot to mention that a flash programmer such as your Superchips doesn't actually replace the entire binary code in the PCM so if you have an "undesirable" PCM code then you are still stuck with that code after programming.
If you go with a chip from PHP, then you will get the latest and greatest PCM base file for your model of truck that has more desirable shifting/torque converter operation.
Hope this helps!
