Got my XRT today. It's awesome. I guess I am going to be in the market for some gauges too. I love the tunes. Has anyone experimented with all the new tunes? What's the difference between the categories? They all have different turbo tuning, but what makes one mild and one wild?

I am running them, but don't exactly know what the difference is. You can obviously tell a huge difference in the turbo tunings, but I don't know about the other categories. I had the wild 175 with aggressive turbo tuning, it was awesome. I am going to try the mild 60 with mild turbo tuning tomorrow. I want to find the best mileage tune and then the best towing tune. I am pretty sure I have already found the racing tune.

H&S does have great customer service. Also, you won't see as many XRT problems when you look around the forum.
