I have a 2000 Dodge Durango with the 4.7 liter V8. Do any of the performance chips actually improve gas mileage significantly?
The chips advertised on the internet for $69 or $79 seem to good to be true, suggesting 20% increases to gas mileage, but tempting with the horrible gas mileage that the Durangos get. Thanks.
