Thanks for the clarification. This copy of TC comes with OBD2_06_01 through OBD2_06_04. I use it for 96-01 Vortec vans in our fleet. Apparently it will not cover the '96 - '97 C/K trucks.
Not sure why it wouldn't. My 1997 Express had the same PCM flash as a 1997 Suburban and some 1996 C1500s. BNHP/BNHR. Back in the day, I kept my stock PCM and reflashed a 96 or 97 4x4 Tahoe PCM to the BNHR after adjustingthe tune.
