V2.1.16 on my '05 MN6 LS2 C6.
Whenever I flash my vette it goes through "Service Engine", "Service Active Handling", etc. This did not occur when I used to flash my C5. Also my average MPG goes to zero and I don't recall that being the case w/ my old C5.
Small things that certainly do not impede my ability to use the product, but worth noting perhaps.
