Can't you already do that if you wanted to leave it plugged in all the time? I've never tried it going down the road but change power levels with it idling all the time
What about changing tunes with a insite? Or do I just need to trade the xrt for a mini max...gonna cost me either way...but they are hard to find and expensive... I got to get gauges either way but I like the xrt a lot better than the SCT tax I had
