im having prob with fuel with my 2000 turbo on a w reg.

i only seem to be getting about 20 miles to gallon with easy driving, could this be cause by the remapped. i did turn the boost up with a bleed valve but took it off until i get a boost controller ever since then it has been bad on fuel i have restet the ecu still no change

 

you don't buy an impreza to get high MPG so don't worry about it.

 

leave the engine running and disconnect your maff sensor and then tell us what happens?
