Found a Bully Dog GT tuner on ebay for a good price the other day so picked it up. Got it today, about to go check it out. I was just seeing if any one else on the forum is running one on their madas and what setting are you running. Also how do you feel about them. I noticed on the Titan forum alot of members are using them and talking about them not so much on here. hope to hear from a couple members input. Later guys.
