    "Wow, I have a Cold Air Intake, 4" Exhaust, Transmission Shift Enhancer and the Triple Dog Downloader. I am getting 26 miles to the gallon on the Crazy Larry Setting. Let me tell you, wow! Now I need a new Bully Dog Allison Tranny. All I have to say is bring it on Cummins and bring it on International!"

    -Chad Lovlin (Grande Prairie

    "The Super Aggressive Allison shift kit is a sled pullers best friend. Super firm, you know it's in gear type feeling. I would not recommend this kit for the street though, for the street better go with the Shift Enhancer Kit. Bully Dog has done their homework!!!"

    -Jimmy Bonham (Lake City, FL)

    "I have a 200 F-250 7.3L with 170,000 miles on the tranny. I installed your shift kit in about 1.5 hours. What a difference! I also have a 6-position chip. When on the high setting the tranny had a harder time shifting at full throttle, but now it's great, quick and firm. I love it, Bully Dog rocks."
    -Frank (Hyattsville, MD)
