So any thoughts? I mean is it feasible that this thing could actually work? I'm trying to figure out if it actually makes any sense. It sounds like the main thing it does is increase the efficiency of the catalytic converter by heating it to operating temp more quickly. But from reading it, I thought it said it increased the throttle position on average by 10%. From using my ScanGauge I've noticed that a higher TP usually means lower gas mileage. Am I going crazy? Or could this thing actually work!?
