i've been thinking that i want the tst powermax but one of my big questions is why doesn't the diesel power mag ever advertise much of their products or talk about them? They all talk about banks and edge and bully dog but why not tst? Other question is, is tst the best chip to get. How is bully dog it seems that they are coming more and more into the diesel world i guess you could say. Edge is ok i guess and banks is just way expensive. Anyway in your guys opinion, which chip would be the best? TST is pretty expensive to but is it worth it?
