    Air intakes and Mileage

    Was interested to see is anyone with Volant, K&N or the Lingenfelter intake systems have experienced an increase in mileage?
    I know the HP should go up and your foot on the gas peddle down but in normal driving did you experience and MPG change for the better.
    Thanks for the input.

    My MPG went down cause I started accelerating much harder so I could hear sic noise mine makes. I think that after any mod that makes a noise, your MPG will go down. At least for me...

    Honestly...who cares about MPG...if you do get a g*d Damn Toyota! I think its fun to see how low I can get it...I cant seam to average below 11.

    I dont really care about the gas mileage as I drive a V and a Vette!
    Just was curious as thought mine went up in the Vette when I installed
    the unit, but I had headers/exhaust etc.

    No, when I went to get it they didnt have any for the LS2 done. I've been on the road so much that I havent had much time. The best I did was 340/331...i need a new tune though...mine didnt take too well.

    Re: Air intakes and Mileage

    If I try I can keep it above 17 (no fun), typically it's around 14 and as low as 13. Never got down to 10 on a tank!

    Looking for a new head/TVS combo next year but I need a quick fix so I was thinking about going with the ported TB and intake. Do you know of anyone that has done this and if so did the butt dyno register any gains?

    Before you get that fancy new tune, put on a set of headers to help her breathe a little better. Need to prove that the LS2 is more then just a truck motor!

    Re: Air intakes and Mileage

    I bought my V from a friend of mine. I helped him install the Ligenfelter CAI when it was still his car. He got 26 mpg on the only road trip he took after installing it. I don't know if it was better than before the CAI, but definitely respectable. I haven't kept my foot out of it enough to get 26 mpg on the 2 road trips I have taken in it.
