Hey guys this is my first tuner for any vehicle I have owned. My truck is a 2012 ram 1500 outdoorsman. I've had it for almost 2 years. Right away I put a 2 inch leveling kit, a 3 inch body lift and 35's on xd spy's. Needless to say the mileage really went down hill. The throttle response and sluggishness were almost unbearable. Surging and lag in the higher gears. So I bought a bullydog gt this weekend and installed the regular tune. My mileage increased dramatically and the truck is way (and I mean way) more drive able. I can feel the extra power and torque easily. Although it's probably not a big gain. But if I had to give a reason to buy this tuner it would be the change in driveability and the transmission changes alone make this worth it. Anyway I know I'm gonna get alot of questions about this because I haven't found anything on any of the forums really that's concrete for or against the tuners. Feel free if I can answer it for you I will. Now that I've driven it a while like this I left all settings stock except for tire size, I'm wondering about tweaks I can do to make it better. Should I adust throttle response? Like I said I left it stock. What about shift points? I guess I'm looking for someone with experience in these tuners and how they have theirs set up and what their results were. I know the hemi fever tune for diablosport adjusts the throttle response more. Any help will be appreciated. And one more thing because I know this will be a question asked. My fuel consumption was anywhere from 18-22 litres/100 kms depending on how often I reset the calculation. Now it's steasy 12-14 litres/100kms. Well worth the money I paid for it
