If You Can't Run With Bully Dog, Stay on the Porch

8. Robert, a Brothers Performance technician, programmed the Dynojet computer prior to the first pull.

9&10. To capture and establish the factory torque and horsepower data, Robert watched the rpm increase as he mashed the throttle after the Dynojet dumped a load on the Duramax during the baseline pull.

11. Referring to the computer monitor, Robert and Stephen checked out the baseline dyno result, which was 248 hp to the rear wheels.

12. Prior to a multitude of dyno pulls at different horsepower settings, Stephen slid behind the wheel and programmed the Power Pub.

13. After a couple of Power Pub pulls, the results were evaluated. A 70hp download resulted in 303 hp, then with a 150hp download, the results were 403 hp.

14. For some real entertainment, Stephen released the horsepower valve of the nitrous oxide bottle.

15&16. Robert observed the Duramax vital signs as he glanced at the Bully Dog boost and exhaust pyrometer gauges encased in the A-pillar molded pods. The Power Pup was programmed to induce a 150hp download with some extra boost injected from the Bully Nitrous Kicker system. The potent combination almost spun the tires off the rollers.

17. After the final grunt pull, with the 150hp download from the Bully Dog Power Pup and the Bully Nitrous Kicker system, the results were very impressive -- 492 hp.

18. Here is Brothers Performance Dynojet Model 248C's baseline pull at 248 hp (1), and here is the pull with the Bully Dog Power Pup 70hp download equalling 303 hp (2).

19. Here is a picture of the Brothers Performance Dynojet Model 248C Bully Dog Power Pup 150hp download equaling 403 hp (3), and the Bully Dog Power Pup 150hp download with Bully Dog Kicker Nitrous Oxide equalling 492-plus hp (4).
