I know that some vehicles, like the Trailblazer for example, seem to have a govenor that controls gas on jackrabbit starts. My TB has 275 hp I6, but I can't catch any rubber. They must be controlling fuel electronically to keep it from getting horrible MPG ratings.
I drive my wife's little Chevy Cavaliar to work most days. She keeps the Trailblazer at home so she can run the little rug-rat around town if she needs to. I get about 33 MPG in the Cavaliar and like about 18 MPG in the Trailblazer.
first the tornado air intake helped but to make the mod complete change the air filter to a k&n high output filter i live in nj and was averaging about 12mpg after these simple changes im now getting close to 17mpg im happy with that alot of stop and go traffic here im sure it would be even better on the highway the tornado ran me $69 and the k&n filter was $50 they are washable and have a lifetime warrenty (compared to a $20 paper filter) gas prices are $2.80 right now for regular so its worth the mod also doesnt void any warrenty parts just slip in
I agree. I don't worry much about trying to get better gas mileage on the beast! That is, I don't worry when I drive it. I've been taking the wife's little Cavaliar for the past year and letting her drive the Trailblazer for groceries. The beast is for the weekends going to the hardware store, etc.
