I'm thinking about putting in a new chip to give the car some additional kick. However, I commute 150 miles a day. What change in fuel economy might I expect with a new chip?
I'm currently averaging about 29 mpg.

thanks

 

Your mpg won;t go down on the highway. Mainly in the city where you tend to have a lead foot between stoplights. My mileage was hardly affected at all when I chipped my car.

 

some say it will actualy increase fuel economy if you dont spend most your time with the pedal to the floor

 

Yeah highway it doesn't affect, but when your on it alot it really eats gas for me atleast.

 

Yeah, didn't change highway mpg for me either. Just when you get into the turbo.
