The kid I bought the truck from said they are Bully Dog 80's. Sitting at cold idle, no KSB engaged, it'd blow about half black, half white/grey, and a goodly amount. I bet it'll roll the coal when you get into it on the street and put a load on the engine. Should find out after Memorial Day. Oo. Building the transmission this weekend, then to start on the D70.
