How HPTuners works is that you first read in your stock program through the diagnostic port and save it on your laptop using the HPTuners interface. Then you edit the stock program using a PCM editor program (comes with HPTuners). Then reload your modifed program. You still have the stock program to reload at any time. It takes less than a minute to load a program to your PCM.
HPTuners also comes with a OBDII scanner that lets you monitor/log all of the PCM parameters (no BCM, ABS, etc.), view diagnostic trouble codes, clear codes, etc. that you can use with any GM OBDII vehicles. For the vehicles that you have licenses for you can control the PCM on the fly. For example, you can change the commanded A/F, timing, turn off/on things like the fuel pump, peform a CASE relearn, cylinder balance, etc.
