I was wondering if there is anyone in Texas (around Austin) that has twin turbos on their truck? Also does anyone know who has a kit for them alredy made up around here-performance diesels of corpus christi? I know some one can tell us exactly how they work-wastegated? Smaller one(size?) feeds big one(size?) and how big can the exhaust pipe be 4"-5"? Truck will have 600hp-24v.
