I have a 2003 lb7 that I am having the transmission built right know with a ppe stage 4 kit and the motor is all stock and looking for a couple really good tunes for this setup. I would like a good heavy tow like 12-15k and then a light tow like 2-7k and then just a good fuel mpg tune. I really wish I could use the dps 5 settings on the edge cts but since cant use them. Would like to see what someone on here can offer me. Otherwise I guess I will have to have someone do them with efilive.
