    Needing to change from the Edge Race and really would like to go with EFI but my MDH is 041712 926AA, ECM # is CM2100A, D/C 04/02/2009. Based off of this I can only assume that I have the locked bootloader.

    Anybody on the Western Slope of Colorado that has a 6.7 Smarty I can use real quick? I know I could go with other options but want the tune-ability of the EFI.

    Thanks in advance!
