Full Bolt Ons- Performance VS. Gas Mileage

[cali yaris]

intake/header/pulleys/exhaust and I dyno'd 108 whp. baseline was 94. My dyno is in the thread where dyno charts are posted.

Mileage wasn't affected for the same kind of driving -- but the point of those mods is to go faster so I drove.... well, faster!!

Header is singular by the way, we have just the one header on our 4-cylinder cars.

x2 Modded Yaris and I even feel I get better MPG. I've been getting 29-33MPG on city driving and I'm ridding on 18"s

Lol , I feel the same way . If I were to drive this car with the intent to get the best mpgs I think stock vs. modded would be @ least equal if not better on mpg's (mabey 1 or 2 more) with modds cause you don't have to get on the gas as much since you have a little more power . I am killing my mpg's with the heavy-ass 18" rims and am still getting around 28-32 soon to be switching to lightweight 15" rims so mpgs should greatly improve .

as long as you dont get bigger injectors, fuel pump, rail, you should be ok, but if you want more power, get a faster car ;)
