Or an egg on top of the accelerator.... Steve, Host |
|
| that got 12 mpg with me driving an 16 (in town) with my wife driving. Go figure. | |
|
Or an egg on top of the accelerator.... Don't suggest that to our Aussie friends! Placing ostrich eggs on the accelerator will cause the vehicle's speed to max out rather quickly! tidester, host |

Drive like you have a egg on your gas peddle and use the brakes as little as Antisapate stop lights) possible. As for testing gismos, test them on a machine/dyno, since driveing to work is not a good way, because you may hit more signals or heaver traffic on ome day more then another. Also you have to figure in the cost of the devise, such as $60 or so how much gas does thay buy. |

I have real world data back from my 2000 Chevy Tahoe Limited ("old" body style), 5.7L V8. I drive a consistent mix of city/highway driving. Before Tornado, I measured my mpg at 14.9 with my previous tank of gas, although I have been known to creep up into 15.0 to 15.5 on some previous tanks. Keeping driving habits the same, my first tank of gas post-Tornado was 14.9 mpg, my second 15.3 mpg. I didn't consider this statistically significant or sufficient to justify the $70 investment, so I disconnected the battery longer than they suggest (5 minutes) to "reprogram" the computer, I presume for air-fuel mix. After reconnecting the battery, started and idled longer than they suggest (2 minutes). So my third tank of gas after the battery trick was 15.3 mpg. I had similar warning bells in my head from reading their marketing material, as previous posters in this forum, but was willing to run my own test under the 30-day money back guarantee. So I still have almost 2 weeks of the 30 days left and plan to remove and return for my refund immediately. Let's say that the device does allow great improvement for the vehicles listed in their marketing material. Even if that were true, there is not a vehicle of the 2000 Tahoe type with a Vortec engine that's represented on their table of example improvements. So I won't be installing it on my wife's 1997 Suburban then either, as it has the same engine type. For Tahoe owners in my area wanting better gas mileage - my advice, cure the lead foot up to your stops and out of your starts. Where are you really going when the light in front of you is still red?

"miracle cure". The only way to lose weight is not through some magical pill or supplement, but through proper diet and exercise. Even though most people know this, the diet industry still grosses over one billion dollars a year. Same for the automotive "economy and performance improvement" market. |

Gas is $1.81 in my area for regular, and Tornado and other gizmo companies are starting to crank up their ads again. Pay attention to the "up to" language when you read the mpg claims Steve, Host |

.. your best bet would be by powerpack kits (includes filter, catback, headers, etc) by gale banks, and if you have a gas engine you still won't have such great mileage. but at least you'll have good power here's a testing for the chevy 5.3: http://www.galebanks.com/test_results_AC07.cfm 24 hp and 22 lb-ft at the *wheels* .. and only %2 better mileage. |

| I find the tachometer in my auto trans car helps me to get better mileage by making me ease off on the gas so trans will upshift sooner into a higher gear but without lugging the engine.Previously thought tachs for an auto trans car was useless(learned to drive when auto trans had only 3 speeds), but with modern torqueless engines having 4-5 sometimes hard to feel speeds and todays quieter engines, the tach allows me see what gear I'm in and adjust the gas. | |
