GREAT PRODUCT

Reviewed By jimmy h (Little Rock, AR) Reviewed for a 2012 GMC Yukon XL —11/8/2012 11:00 AM

AFTER INSTALING THE PROGRAM IT HAS RAISED MY FUEL MILAGE UP TO 17-18 IN TOWN AND IT DOES NOT SOUND LIKE YOU ARE DRAG RACEING SOMEONE WHEN YOU TRY TO ACCELARATE IT ONLY SHIFTS DOWN ONE GEAR INSTEAD OF THREE AND TACKING OUT.

So easy!

Literally pulled it out of the package and plugged into the ECU. Took 5 seconds and its working. After experiencing what detrimental effects AFM has on a vehicle, this was a no brainer!

Reviewed By Anthony L (Gig Harbor, WA) Reviewed for a 2000 GMC Yukon XL —10/7/2015 8:47 AM

So far I have put about a thousand miles on my 2000Yukon XL with the bullydog and fuel averages went from fifteen to eighteen combined with a noticeable difference in performance of throttle response. It seems like in time the Bullydog will pay for itself and make the truck more usable with both power and MPG increases. Auto anything did a great job on price and getting it here quickly once again. I would definatly recommend this product to anyone and suggest auto anything as he place to get it.
