What do you think my truck should be running in the 1/8 or 1/4 with its current mods of Black Bear Auto-Cal tune 91 octane, Airaid M.I.T., AEM dry panel filter (oem/factory type), and Magnaflow 3" SI/SO 14" case muffler?
The only thing close to a baseline that I have is that 2004 Car & Driver article that showed a Silverado Z-71 identical to mine (same gears, engine, trans, and even tire size) that ran a 1/4 time of 16.8 sec.
How much of a difference should I expect from the BB Auto-Cal 91 octane tune?

Really hard for me to say and by no means do I mean any disrespect whatsoever. I seem to recall that I saw new era on the project thread .7 (1/4) just from a tune although it was 2012 5.3 4wd & 6pd. I think it was 15.9 to 15.2 iirc bone stock. I know your tune is probably less aggressive but with the muffler and the intake I would've thought a bit better. Wish I could be more helpful I'm just thinking the tune is a bit off.
I re-read that New Era build thread last night, and he did see a significant drop in E.T. with his tune. Awesome truck too!
BB's website said they're out of pocket this week (by phone), so I guess I'll call them next week.

I had a 05 crew cab 2wd 5.3. I had 4.56s, magnaflow muffler, shortie headers, cai, and superchips tuner. I eventually did more things to it, but in this config it went 14.79 at 93 mph, and dynoed 279 rwhp on 20s. i think it ran 9.4s in the 8th at 74 if i remember. Your heavier. To compare that truck, my bone stock crew max tundra ran 14.6 at 93 lol.

Well, first off I feel like a dope because the time slips I posted in post #12 of this thread I made WITHOUT having installed my Black Bear 91+ Octane tune! DOH! That's what I get for being technically challenged. I thought the tune was installed but come to find out it wasn't and it was completely my fault.
Now I get to go back to the track to see what difference the tune made since it is installed now. I can't wait to see what it'll run now as it feels like a completely different truck with the tune installed! I just have to wait for another 61*F day to go, which will be a while.
So...this is what my truck had done to it when the following passes where made. For whatever reason the 1/4 trap speed wasn't working. Temp was 61*F. Like I said, she's fat and slow.
2004 Chevy Crew Cab Short Bed Z-71 4wd 5.3L LM7 / 4L60E / 3.73 gears
Magnaflow Muffler # 11229 3” SI/SO
AEM Pro Flow Dry Air Filter (oem panel style)
Airaid M.I.T.
left off idle,
left @ 1,200 rpm,
