I have been messing around with the setting and it seem like E/2 is the best setting so far. There is a difference in power especially low end. The sport display will not go over a certain HP or TQ. Seem like it maxed out at 260 hp and 430 tq no matter what setting I changed on the tune. But I was able to use my PLX Kiwi device and Dash Command app on my iPhone. This is what the Dash Command app read. I don't know how accurate this app is, but all data including wheels, tires, curb weight, passenger weight, and fuel capacity has been inputed. The result seem pretty crazy.
