"The easiest thing I have ever installed on a vehicle. Had it for two weeks not sure about better fuel economy yet, if it is better its not by much but there is a big difference in power. I also added a volant cold air intake with ram air scoop and magnaflow exhaust and wow its like a whole different truck. Overall I am happy with the triple dog tuner and would recommend it" —David A from Brevard, NC bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2007 GMC Sierra.
