The Power Pup increases horsepower and torque by re-flashing the vehicle's Engine Control Unit (ECU). Installation takes place in-cab by plugging the Power Pup into the OBDII port. The Power Pup gives the user four horsepower settings to choose from: Stock, Tow (50-70 hp), Performance (75-90 hp) or Extreme (95-230 hp). The Power Pup retains the stock program so the truck can be put back to the original settings if the need arises. There is a 'Crazy Larry' download of +230 hp for some vehicle applications.

Testamonial: I just got my Power Pup downloader tonight and put it in my '01 GM Duramax. I cannot believe it. I only put in the #1 tune and it ran like a bear or should I say a Bully Dog. This is the coolest thing I ever saw. It took no time at all and what time I did spend was unhooking a competitor's product that did not work. It would jerk like crazy when pulling my 48ft. car and living quarters trailer. Unlike the Bully Dog which has more power and low end torque and is smooth as silk. All my Duramax friends will want this downloader. I came home last night with the trailer at 70 to 75 mph like I was pulling nothing. Thanks again I am very happy with Bully Dog! - John Shrewbusry -- Pontiac, IL
