Very Cool! I had lean burn setup on my 05 Cadillac CTS-V. It landed me about a 10% improvement at speed. I could watch my live MPG read out while it was switched on and off with the tuning software. Mine didn't kick on until the engine was over 180 degrees. I also had some extremely aggressive DFCO settings on.
