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!

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

The tune you posted here is a 2004 truck calibration in a 1mb PCM. Does your truck have a 2004 COS?
