Default newer 5.3 intake on lq4

wondering how many have done this swap? i am using a newer 5.3 truck intake on 03 lq4 cable throttle body. found an intake cheap and scored a 90mm throttle body. wondering if anyone else has done this and noticed an improvement? swap was fairly straight forward will be firing it up tomo hopefully

I know someone who has an 04 lq4 running the newer 07+ intake with a 90mm throttle body, and he says he can really feel a difference.
