are you sure on your numbers here? i just read that stangkilr ran a 13.5 on a tune only 6.2/6l80e. if he was spraying a 100 shot i would bet he would be deep into the 12's. if not flirting with 11's.

take a look at dlt's post of just the lt's CAI and tune did to that denali

this is what i would recommend, do those two and you should be well happy with the results. listen to dlt. a retune would "not be necessary" but highly recommend with those mods.
