I've just recently installed the Banks Six Gun Tuner with the IQ and I really like it. I've done the whole thing of installing analog gauges, and while I like the look of them, I really like the IQ due to the fact that you can monitor so many different things. Plus, you don't have the headache of hooking everything up, and running wires, lines, hoses, etc... And you can also change the style of the gauges on the screen as well, just to change up the look of it. I don't tow a whole lot, but Banks does have the Speedbrake, that will work with the IQ, and supposedly it works well for towing heavy loads by adjusting the vanes on the turbo. Just throwing out my $0.02.
