i like the ones i have recieved from Rob at Rob's Diesel. i know mine is a ppump 24v, but i have a benched 215, 7x12 injectors, 100 plate, and a 66mm. egts dropped 50-100* cruising and picked up roughly 100 miles per tank. i went from so .020 dv's to these and love them so far. still got to go back to the dyno to see the difference on the rollers
