friends got a powerstroke with some banks goodies, a bigger turbo, intercooler, piping, exhaust and a nifty gadget called dial a boost.
a little knob on the dash with 4 presets stock-faster-faster-fastest
its pretty neat because the fastest setting consumed the most fuel but makes the most power, stock consumed the least fuel but makes the least power, so you dial up enough boost as you need to get the job done.
his truck is a dualie with 4 wheel drive and he does 4 wheel burnouts down the street, its impressive.
