Not to be smart, but it was probably your speed, and fear of losing a wheel on the highway. I know I was like that when I lost a lug on my Celica.

Any Performance Item that adds Horsepower and Torque will give better gas mileage Depending on your driving habits. With more power your engine does not have to work as hard to perform the same amount of work. Manufacturers don’t like to post MPG #’s because again it all depends on Driving habits, ie Your Foot. Even products that claim an increase in MPG don't give an exact #, Not even the MPG Listed on your window sticker is exact.

I put on a TRD Air Intake and my MPG's went down to 12.6 to 12.9, nearly one gallon less per mile. I also just put a Magnaflow exhaust. I am thinking about putting my old air intake, I don't really know what to do. Does this sound right? Any suggestions? I thought with the TRD Intake and the Magnaflow I might get a little better MPGs. I difintely didn't think less. Thanks for any input.

Just some questions I would ask myself to help pinpoint the problem...

Did you put the exhaust on at the same time as the intake?
How Long have you had the intake on (days/miles driven)?

Did you weld the exhaust system or use the supplied clamps?

I would check the exhaust system for any leaks, a drop in backpressure can actually make you lose bottom end Torque and Horsepower.

The computer system might need more time to recalibrate itself.
