Not talking about a cheap hand held tuner, I'm talking about the "VXDIAG GM" module (which is like a Bosch VCI)...and using GM's software on a PC to flash (or re-flash) a module....using Tech2Win or GDS2.

Now maybe VXDIAG is cheap, but if it has full J2534 functionalty, why spend $1500+ on a Bosch VCI.

I'll post a link again so long as the moderator doesn't delete it. Otherwise Google "VXDIAG GM".
