can i data log for a better tune?

[07hemi]

if i use the data logging that is on the diablosport predator could that be used and sent to a cmr custom tuner to make a better tune? and also i have a custom tune now for my truck but i just got long tube headers installed and was told i needed a new custom tune. is that true?
