Appears to be a unused Haibeck Tune for the 93 and up cars.....

Will try and find out more details

The performance calibration BMCBG is based on GM’s latest release of the calibration for ’93 to ‘95 LT5 engines. GM calibration BMCB was released as a service part via Product Service Bulletin 576514 dated 18 September, 1995. It was released to address a problem with sag or surge on light throttle acceleration below 2500 RPM. BMCB also includes the previously released revision to the ’93 and early ’94 production calibrations, BKKR. BKKR was released via Product Service Bulletin 475001 dated 24 January, 1994. It was provided to solve a problem with intermittent “Service ABS/ASR” errors that some cars encountered at startup.
