Someone just took a dmax to a dyno and did a comparison between stock injectors, and a small (40-50hp) injector swap. It's a mostly stock dmax with a programmer.. He gained 25-30 hp at the wheels, picked up 1.5 mpg, and dropped cruising EGT's 150 degrees.. The writeup is over on compd.. Even if you're not looking for max power, it sounds pretty good.. More power, less egt's, and better mileage are good results..
