I don't know if I should be discouraged by the 5.3 and save for a 6.2 swap or mod the 5.3 I want bottom 13's to high 12's
My old 2006 rcsb Sierra did consistent 13.3@102mph with a stock LQ4 with bolt on's and I was happy with that

Congrats on the buy A tune drop in K&N and a cutout will drop those times. If 12-13s is all your looking for keep the 5.3. A tune alone will wake up that truck alot especially since you have the 6 speed behind it.

Yeah I noticed it had not two but three cat's on it
I'm sure longtubes and exhaust would help it out a lot. I'm lost on these new trucks there are more changes than I though

My buddies truck was running about the same time (2wd ecsb) before he put smaller tires on it, did servos and shift kit, longtubes and ORY. Give it some more time to loosen up, get some simple bolt-ons with a tune and you will be low 9s with ease
