Where did you buy it from? Most vendors offer a tune or two with purchase. The cool feature about efi is that you can compare tunes to see what was changed and where so you can kind of get the hang of it.

LMM have a programming history feature where the dealer can tell if you have flashed your truck's ECM. The only way currently to not have any history on you ECM is to purchase a new ECM and flash it with efi so that your stocker does not show the history.

the only issue i see with doing the ecm swap is you have to find one and then have someone with a tech 2 flash it with programming to your truck. efi can full flash the lbz/lmm ecm yet as far as i know. but like kat said if guy tripp has them i know he has a tech 2 and they may be flashed already. call him. dont risk your warranty on a foolish tune when you have options. remember your warranty is 100,000 miles.
