Print the COS Tutorial ... read it several times ... and make some notes about the necessary steps. It is actually very straight forward.

Do you have a 2 bar (or 3 bar) MAP sensor fitted ? The stock 5.3L 1 bar MAP is useless under boost conditions.

If you are using EFILive for this project, you may want to consider posting on their Forum to get support with respect to the COS upgrade.

yea it still has the 1 bar going to order the 2 bar today and try to get this figured out i have the same set up on my silverado ss it works fine on it guess just got lucky with it but this one flattens out around 4500

You really need the Custom Operating System and 2-3 bar MAP to tune it properly... as stated already.

You may just be lucky it worked on the other setup? Maybe it's melting slowly? It's not tuned correctly though.

This new one may be just running out of fuel? For what ever reason it does not matter, you should stop!

ordering 52 pound injectors and a map sensor now just ran off the instructions for the custom os might need alittle help setting it up but im going to give it a shot

Make sure you get injector data that can be understood and entered into the calibration.
