Whatever name they go by, does anyone do programming for the 2011+ cars that allows on-the-fly program switching with the stock ECU? I've seen it done with older cars and I do it with EFI Live on GM products. I'd love to have the same feature for my 2013 GT. Right now, I have to use my SCT handheld to swap back and forth between my 91 Octane and my N2O tune. It'd be great to have something that swaps maps as soon as it sees a 12v+ or Ground signal, similar to EFI Live.
