Can the older black box pcm's be full flashed and change from a V6 OS to a V8 OS...I have a pcm that I used a license on(vortec V6), I'm about to do a motor swap using a 1998 5.7 Vortec and was wondering if I can just do a full flash and change it to a V8 so I don't burn another license...
I ask because I've only full flashed the LS1 PCM's and change from a V6 OS to a V8 OS all the time...
