RB25DET terrible mpg

[.blank cd]

This is a strange post.

The S14 I acquired has an RB25DET, SAFC, front mount, boost controller and exhaust. Puts out 317 to the wheels. Pretty nice power band.

It gets like 200 miles per tank if your easy on it. And like 110 your NOT easy on it.

Could this be a tuning issue? Its on a stock turbo. I know with more air comes more fuel, but would a turbo upgrade help this out?

...Suggestions...?

On a real note, are you serious? what do you expect from a boosted 6 cylinder? a super-green 35 mpg? Get a daily driver homes

No I don't expect the gas mileage of a civic.

Its a turbo 2 liter. And after reading up on Nico forums, some guys are getting 28 if your not on it. The average is about 23-25 on the highway if tuned right.



Oh and what dos a boosted 6cylinder have to do with it? My 400 hp turbo 8 cylinder gets 21.6 on the highway cruising at 76 mph.
