Celica Forums General Discussion Exterior Intake=more gas?

Before I installed Intake, I could go 360~390 miles with full tank (GT), but after I install Intake, i could only go about 320 with full tank. I am not sure is it because i turn on AC recently or because of Intake.

intake, exhaust, headers, etc will take away from miles per gallon, same thing has happened to me with my Intake and exhaust...

AC also makes a big difference.

It shouldn't, unless you are running rich due to the movement of the MAF sensor or an incorrect hookup or leak somewhere.

My gas mileage improved considerably after I added my exhaust. Could be a unique experience though. I just figure that freed up horsepower would allow the engine to perform easier.

it should have give you more milage theoryotically..

i thought it takes away gas milage

it gives you better gas mileage. the ecu will tune itself for the new mod and better combustion of gas and air. ur gonna get better gas mileage on normal drive, but worst gas mileage if you gun it all the time

im pretty sure you are driving harder ever since you got you Intake. i know i have, just to hear the sound of air.
that's pretty much why you have less gas mileage.
not only that if you ahve cai, you tend to loose low-end power, therefor you hit the gas little bit harder to go as fast as stock did.

Dont you wanna reset your ecu so that it knows you have installed Intake, and can adjust the air/fuel?

i noticed this too... when i installed my exhaust my gas milage went way up... but after the Intake it seemed like that it went down a bit

dam i never get high gas milage. the most i get is around 300-320
