Bully Dog Tuner
I was looking to buy one of the cheaper tuners and was convinced to spend the extra money on the Bully Dog. I am BEYOND satisfied with my purchase!! Increased gas mileage as well as noticeable power increase. This unit teamed with the Dynomax cat back system and K&N cold air intake on my 2005 Silverado is AMAZING!! Thanks AutoAnything!
It's okay and works as intended. 5.3 chevy
87 octane tune does seem to open up some power. 87 Tune has VERY hard shifts. Had to contact customer service. (Great customer service -Mike) He sent me a custom tune to fix that. 91 octane tune had very little difference compared to the 87. My truck was running rich with 91 tune using 91 octane fuel. Switched over to 87 running great! I input the actual size of my tires and it set my speedo -5. Very inaccurate. Had to adjust size to calibrate it. Autoanything has the best price for intune. Thnx
