I recognize you from the FTE forums.

To get your questions out of the way.

1. Yes. There are numerous ways to read the existing memory from the PCM. There won't be any data as far as what brand of programming it is, but the data can be compared to a stock file to get an approximate HP level.

2. No. The only thing that really matters is the actual hardware (PCM). No matter what "tune" has been flashed to the PCM, the PCM is still the governing factor on what tuning will be used for the chip.

3. It's not going to matter. Just know that you're not stock when you're "chipless".
