Will a gas engine chip get me better gas millage?

Question

Someone told me there is a chip to give you better gas millage in your gar. How much do they cost? Do they really work and are the really worth the price and installation? Where can they be purchased?

Answer 1

No, stay away from anything like that.  First of all they are probably just tiny diodes that do nothing, or they will actually make it worse for your engine.  Your best bet for an add on would be a cold air intake.

Answer 2

hmm an 01 vehicle look into a programmer that plugs into the obd2 port. superchips has a new unit called the mileage xs. check to see if it is available for your car.

Answer 3

I would be skeptical - car manufacturers tune the OEM chip to deliver the best mpg. An aftermarket chip is typically installed to increase power.

If you want better mpg, switch to synthetic oil, accelerate moderately [opposed to quickly] and maintain tire pressure.
