Purchased 6.7 tuned w/o tuner

[Darektylka]

I purchased a 2007.5 6.7L mega cab few weeks ago deleted and tuned but without the tuner. Can I just get efilive or hs and just tune the truck? will it just override the current tune?

Thanks in advance

correct all they need is the os and you can flash over the tune.

Yes, when you get EFILive you will see that when you go to flash a tune a prompt will say "erasing" which will erase what is currently in the ecm and overwrite it with the EFILive tune you are flashing in.
