I'm working on an older box truck that had a TBI 5.7 with a 4l80 trans. Has any of you guys ever heard of gm service # 16213505 with bin code BNKR? I need to get my hand on the .XDF file is there if it exists. I call myself looking at all the gm ECM files here but it is very possible I could have missed some somewhere.

Thanks,
Dewayne
