I just bought an 06 Silverado 1500 and the tune looks horrible. It only has 9* total timing and a bunch of other stuff I want to change. Mostly for efficiency. Now, I can down load the tune and read it with my V1. It also data logs. My question is, can I upload a tune if I buy a liscense for it? I had to use the 04-07 LM7 V8-Hybrid controller to view it. Does the V1 support the LM7? I have some mods planned and want to be able to tune for them when I get them.
