    ya the drill mod will help you shift faster, well atleast going in third...thats when the line typically restricts the most fluid. one of GMs ideas to try softening the blow to the damn 10 bolt. the bump stop mod is where you grind off part of your throttle body "bump stop" to allow the butterfly valve to open farther than stock WOT. it just allows more air to the intake, but dont take too much off.
