What gear ratio does your Tahoe have? 3.42 would be my assumption.

You should look into 4.10 gears. I had an 05 Tahoe with the 5.3 and 4.10's that thing never cared what was behind it. I also had a custom PCM tune in it.

Just a thought.

I would suggest you send your PCM off to have it programmed for the 6.0 vs the Diablo. And possibly check into having some better guts put in your 4L60, it would probably be the next weakest link.
