running rich help

[cefiro]

just wondering if anyone can help with my car RB20 cefiro, has a few mods but its running through was so much petrol maybe going through 20 l per 100km at times, not flooring it that much.

mods are bosch feul pump, I think the o2 sensor has been changes and aftermarket turbo and exhaust and has an afc but not tunned. any one got any suggestions on what I can do/have a look at????

thanks

what size is the tank on the rb20

from my experience you should get about 350 - 400 out of an rb20 tank
