The Hahn is actually a plug & play...Bought the kit, had it professionally installed ($1400), added a glass pack muffler & duals & now she runs like a deer. I only use 4# of boost so no intercooler at present. 10,000 miles with the turbo including a cross country trip of almost 6,000 miles through the desert in mid summer with NO problems (other than heat build up after shutdow which I am curing with a louvered hood). I've had to make a few minor adjustments to the fuel pressure when the weather changes but that's probably not really necessary. For trouble free/go fast, go turbo.
