ok i pulled a 04 montie stock l67 bin off bills drop box and in TT it looks the same as the 03 regal bin i posted pics of.

if you want to send me a pcm for your car i can flash this bin to it with the rear o2 shut off. then once you read it with hp its set up that way forever.

dhp will let me set your vin # so hp has no issues with the pcm too. if you know your osid # i can try to match that as well, then ive found two times you dont even need a security learn if that matches.
