got it. forgot I had tuned a couple already. do I have to have the VIN in the tune on an LMM I didn't shut the VATS off so would that be an Issue? or can I just use the LMM OS from another LMM and flash it in? I knwo the right way is to enter the VIN from the rig that is getting tuned but the guy never got the VIN to me and if he wants this tuner by friday I need to ship the auto Cal by today or tomorrow at the lastest and next day it.
