I read on another forum that the Bully Dog will not work on FFV. Is this true? Is the timing advance recommended on FFV? Whats the difference between the regular gas vehicles and FFV?

flex fuel vehicles can use ethanol. ive seen posts on here from SCR and pops showing that that gas was not saving anything.

my 08 is a FFV and i use the pup on it. i definitely notice a difference. i use chevron 93 and the pup premium tune. id like to see the link to the other forum so i can call them out! lol

It was a PM to someone selling their BD PP. They said that it would not work for FFV.
