Just wanted to say thanks. Tuned my dads LBZ and moms E38/T43 silverado and could not be happier with your product. I do realize I have a lot more to learn about it, but you have made it as easy to understand as I think anyone could. My mom finally enjoys driving her truck and to quote my dad "it (his LBZ) just runs like its always in a tailwind"

Now, would you please hurry up and release the 03-05 5.9 capability! I'm ready to tune mine!
