I bought a Diablo i3 tuner for my truck and I'm pretty happy with the results. The throttle is more responsive and transmission doesn't seem to search for gears like it used to. I have an 08 M6 and I am pretty happy with it already. My question is is it worth it to pay an extra $150 to be able to tune it as well? What kind of changes should I expect to feel?? Its a manual so changing gears is all on me. I wanted to hear from others that may have used it and what their experience has been.

You'll pick up a solid 20 rwhp on the LS3 with the provided tunes.
Before you spend the money, put the Tahoe back to stock then load the tune to the Vette.
If you love it, which I expect you will, then buy the 2nd license so you can tune both
