Default tunning a 5.3 colorado

Has anyone on here tuned one of these trucks and if so was there a noticeable gain. Mine is a 09 non vvt with a k@n filter and deleted resonators. Dont want to waste my money if not much difference

I have tuned several unfortunately all of them were street tuned so I dont have any dyno tuners. On a 5.3's you usually gain 15-25 rwhp from tuning alone.
