OK.......so this is my first post, and yes I am a corvette guy, (thats a OLD corvette guy) so don't burn me to bad. I have looked at all the thread that I could find. So is there a programmer, tuner chip, or anything that will HELP with MPG. I'm going to do a cold air intake and do something about the sound.......or thats no sound.....can a hemi sound that bad?[:'(] so anyway, please feel free to tell me what you think. Thanks.

 

I have the same question. The only thing that I have seen work well so far, is a throttle body spacer. I friend has on with the helix pattern on the ID (kinda like the gas tornado) and has seen about a 10% increase in MPG. Not bad for $80.
