hey im new to this forum, my wife just got a 2010 cts-v and we really like the car alot except for the mileage. i know, i know before anyone says it, we knew it was going to be bad before we got it but i was just wondering, are there some things that can be done to these things to get a little better mileage out of them? thanks for any help.
ok, well thats kinda what i thought a lot of you would say, and thats fine but does like an cai and cat back exhaust help any? i have efi live, can i get a tune of some sort that would help some?
