Got my DSP5 Tune, switch, and efi installed..now how?

[bgray]

K, I have all my stuff done to get the dsp5 setup running. I know this is a newbie question, but im lost. I open my Duramaxtuners dsp5 file and it opens the EFI live tune program. once i have my autocal hooked up in the truck and ready to do, Do i simply just use the red arrow download button and download it all to my ecm? Or do i need to upgrade my ecm to dsp5 first?

when i open the duramaxtuners file in the tune program, it shows my OS as 52628594....so i pressume its already ugraded to dsp5 and i dont need do the dsp5 upgrade...just go ahead and flash the tune file to my ecm?

thanks
