What would be a good choice for a programmer/tunner for an LB7? I'm not going to get real trick. I pull and enclosed trailer and have put on 285/16's. I don't plan on getting to trick with the truck. I have the banks exhaust and that is it. I want to be able to adjust my speedo and top speed limiter plus be able to get a few more HP and MPG. What do you guys think?
