The BMS JB Stage1 uses a similar technique to fool the DME but with addl sensor data available to it has a more sophisticated algorithm.
The Stage2 upgrade kit is basically a new control box and 4 extra wires that plug in to give the tune full CAN access. Which opens up a whole new world on the tuning end. I'm hoping they will do some dyno testing next week for me to share. Their 328 has had the Stage2 BETA on it for a couple weeks now.

Mike, will the Stage 2 add more hp/lb-ft? Or just new features?
