From my understanding, a proper tune will improve both your power and MPGs. The stock tune is best for tailpipe emissions (always a trade off for everything). That said remember the stock tune is not the best for any car, it is for the median of what the manufacturer has as the tolerances. Every engine that rolls off the line is slightly different even with today's much tighter tolerances, all the tunes are the same.

So, with wanting a custom tune for fuel efficiency, would I just walk in to a reputable shop and say "I want a custom tune to maximize fuel efficiency?"
Also, can the stock fuel map be overwritten, or do you have to buy a custom ECM? |

We took a Tahoe straight from the dealership because the guy wanted a tune and gained 20 hp and I'm sure much better MPG... Also, make sure they save your stock tune... if you do have to go back in for warranty work they can put it back on and chances are you won't have any problems... especially since you're not doing extensive mods they won't even look to see if it's ever been tuned. |

That being said, I just love how some guys think that in 2 weeks (the time it took for the first recalibrations to come out after the Camaro launch) somebody can come up with a calibration that is better than GMs engieers take to do in 2 years. Keep in mind, GM is calibrating the engine for far more conditions, heat, cold, humidity and engine loads, trailering etc. to achieve the best overall BALANCE for FE and emissios. Baker Grade with a trailer on a 110 degree day all the way to a -40 Degree F start in Kapuskasing. If you knew how much GM is willing to pay for only .1 MPG in any car or truck you would realize this isn't as simple as advertised. So to get 2, 3 or 4 MPG more means you are giving up something that impacts emissions or durability or overall driveability under the full bandwidth of temperatures and humidity that GM wasn't willing to trade off. The best example I can give you is the GMPP calibration I have in my Sky. It's GM developed and maintains my warranty. But I also know what the tradeoff is for having it. But in Solstice/Sky land, that calibration is farrr to mild.

Look at this comparison for fuel economy numbers: 2010 Ford Mustang (4.0L V6, auto): 16/24 2010 Chevy Camaro SS (6.2L V8, auto): 16/25 The Camaro SS has an extra 190 horsepower over the 2010 Mustang V6 and trumps it by 1 extra mpg on the highway. |

ok a performance tune will add HP/MPG on a stock camaro. i added CAI, headers and a custom tune and that added HP and MPG. best thing for you is get a CAI and a custom tune.

The only way that tunning a stock car can produce more HP is by making it burn fuel more efficiently, more efficient fuel burn usually goes hand in hand with better fuel economy, untill you jump on the gas pedal, best of both worlds IMHO, problem is the warranty.

Why not just buy a second ECM and load the tune on there. Time for engine work, throw the original ecm in.
