mpg question

[skinnykenny84]

I am currently in the process of getting an eprom and having it chipped. But for now I am getting terrible gas milage. This started hapnen when I put my down pipe on. I am only running 14-15psi but I have stock fuel pump, injectors, and no tuning. Could this be why my mpg is almost cut in half since d.p. install? list of mods in profile

did you reset the ecu after the install? also make sure that all your intercooler pipes are nice and tight!

Terrible gas mileage usually comes from an O2 sensor problem. How old is the O2 sensor in the O2 sensor housing( right after the turbo)? You may have damaged it, or the wiring during the install. Or it may have just died I believe there are ground straps on the exhaust, sometimes those being broken can cause O2 sensor issues.
