Stock 5.3L w/AEM CAI. Stock tune,265/70/17 4 ply tires.
Corrected 250HP/276 torque
Uncorrected 257HP/284 torque,a fair day 70's
This morning.
Now I have a mild 6.0L LQ9.
Comp Cam 208/212 .554/558 lift , LS6 Valve springs,Dynatech 1.75 long tube headers with dynatech y-pipe with cats.Corsa sport exhaust,AEM CAI,42 lbs injectors.Custom tune 26 degrees of timing AFR 12.6.
285/70/17 10 ply tires.3.73 ratio.
Corrected 315HP/327 torque
Uncorrected 329HP/342 torque,cool day, 40's
Have a TVS1900 on the way,I wanted to get some numbers first.
Let me know if these numbers sounds right.
The dyno is a Dynojet.
Thanks for looking.

On a 5.3 with the same cam I put down 280/280 on a Dyno Dynamics dyno. Corrected to around a Dynojets inflated numbers that would be 322/322. Do you have a dyno graph you can post? What gear did you do the pulls in?
5.3 2wd rcsb
CAI
Mid length headers 1 5/8 pri to 2.5 col
Mandrel 2.5 exh
Same cam
Tune
245/65/17 w/ 3.42 gears
Their is a lot of variable so comparing different dynos and dyno graphs from other locations and vehicles will vary. Their will be a ballpark range though unless someone if posting false readings. Dyno's are tuning tools so I wouldn't get hung up on numbers.

I double checked my tune,I have 24 degrees and not 26.
But I noticed that I have a dip around 4600-5200.It may have sparked knocked just a bit.
I should have brought my HP tuners to log the runs.

Not bad. I'd expect more out of your setup with that 6.0 though. That cam pulls a good torque curve in the 5.3 and 6.0. The torque pulls a lot longer than the stock cam too.
Here's my graph if interested.

Logged today,
have some knock on top end at 4400RPM and up.
I guess that is why the dyno results was a little weird at that RPM range.
I backed her off a bit for now.I haven't touch the tune in about a year now.Time to get to work.
