AirDog 1 is for stock to mild. AirDog 2 is their 'race spec' offering, pumps 50% more fuel than the 1, but causes problems in a stock truck as the stock fuel return line cannot cope with the volume of fuel NOT being used by the engine - resulting in a pressure build up.

Brian, with your truck you'd probably have to go for the Air Dog 2 and upgrade your fuel return line for when you're NOT pushing the pedal to the floor! When you did push it, the extra volume from 2 would cope with your engine's fuel demands.

One other question, that fuel bowl delete kit you posted, does that have a 1/4 inch NPT port for a fuel gauge?
