    Any bolt-ons that improved the V's fuel economy? Myth or fact

    Yes it's sounds like a foolish thought to consider when you've got 556hp in factory form under the hood! And yes I didn't get my V because it got great fuel economy so don't tell me to go drive something else. I've modded mostly all of my N/A musclecars in the past with simple bolt-ons like freer air intakes, headers, catbacks and tuning that improved performance and sometimes it help improved mpg's.

    This is my first boosted vehicle and I love how it can outrun nearly 90% of the daily driven cars out there so more power isn't a huge concern right now. So I was wondering if there's any V owners that have done any minor bolts-on seen a slight increase in mpgs.

    Thanks in advance for any good input!

    I'll keep it short: myth. It's the best 12 MPG you'll ever drive though.

    Move the seat all the way back until you can just barely reach the gas pedal. Then hit save in your seat memory. Don't blame me when the brakes don't work though.

    Change your final drive. Otherwise, nothing will get you anything noticeable...

    Again with this? It's a V!!!

    My car gets ~18-20 combined, 12 if you have fun whenever possible. Lets trade. You get a few more MPG, I get 250+ more HP and RWD, everybody's happy.

    Keep the tires inflated to slightly above the 32 psi spec. That will help some.

    outrun nearly 90% of daily drivers????

    More like 99.9%

    Engine tuners for the LSA say the stock V runs a little rich. But that is for safety against detonation. When they tune the air fuel ratio for a particular set up of just air intake and exhaust(headers), they have found they can lean it out a little. Some people have reported better MPG.

    But if you get a bad tank of gas, you might lose a piston.

    All the money you spend on doing this for the sake of increased MPG, you could just spend on gas.

    Enjoy your bullet proof stock LSA.

    See you at the pump.

    Re: Any bolt-ons that improved the V's fuel economy? Myth or fact

    lol...I figured this would probably stir up all the part time internet comedians! Thanks guys but please keep your day jobs!

    So for those who posted real responses it's possible with some pcm tuning could improve mpg's? So theres no other bolt-on that will yield a slight increase in overall mileage? Seriously, I knew this car wasn't meant for sipping gas but guzzling down a tank and getting only 170-200 miles per tank seems extremely low. Heck my 2002 Trans Am gets better mileage per tank but its also less fun to play with than the V!

    Maybe I should just set the NAV to every gas station that's within 170 miles after each fill up. lol

    What final gear ratio would yield noticeable gains?

    The CTS-V gas mileage is so Micky Mouse.

    Re: Any bolt-ons that improved the V's fuel economy? Myth or fact

    by getting a good custom tune that includes part-throttle road tuning, you can increase your mileage. Anything like an intake, headers,exhaust would help if you had this done when you got the tune. The part throttle tune will include leaning it out in certain cruising cells, and increasing timing as well. Is it worth it just for gas mileage, no, but if you are getting a custom tune anyway it is a benefit.

    Plus you put your powertrain warranty at risk by getting a tune.....not worth it imo to save a couple bucks on gas every tank.

    Just put a rock under the accelerator so you can reach the brakes too.

    I will guarantee 1-3 MPG improvement with the installation of the RX oil separating PCV system. Make this guarantee all the time to fleet owners and do the first one free to prove it. Never have had one not have the entire fleet get them.
