Looking for an 06 Avalanche tune

[mvvette97]

My buddy want me to see if I can make his tranny shift a little better and maybe get a little more power. He has a cold air kit and exhaust but that's about it. Does anybody have a tune similar?

what can I do to this stock tune to make it better? I was thinking maybe fueling and tranny. I don't think I should do any timing changes because it seems to ping a little the way it is.
