I have a 2001 ss camaro, I had trouble with the LS1, somehow the block had cracked, so i replaced it with a LS2 from a 2006 wrecked corvette. I got the cpu and had it programmed. I still average 20 to 22 mpg on the highway with an 6speed tranny. I think chevy can do the same thing in the new camaro with the LS3, and even more with the V6. Without adding a stupid 4 cylinder to the options.
