I got a Hypertech III Programmer for cheap so I bought it and stuck it on my truck. About the only good it did was re-calibrate for my bigger tires. You can tell some performance gain. My question is, I have a Comp box coming for my truck would it be ok to leave the Hypertech on there and turn it down to stage one or should I pull it off?
