    Default no power some times but alot of power days

    sry for posting about turbos, even tho it said no more, but i did see anyhting that could help me,
    ok well my car runs good some times then runs liek crop sometimes,my set up is a T3 turbo with custom I/C piping, intercooler, FMU, stock injectors, running 8psi, and some times when i get on it at low RPM's it cuts out like there is noe gas but then it will kick bac in and have alot of power, but ti doesn't always happen, when it happeens the A/F gauge is at rich, then it cuts out , droppes out of lean and it kicks in like nitrous would, then the A/f gauge dont work anymore, does anyone have any idea what it could be, my cheak engine light is on too, and it says it from the o2, but i dont knwo if that would cause my problems, thanxs to helping
    turbo is liek ur old lady, once she starts suckin she dont wanna stop.

    Had the exact same problem, but mine didn't throw any codes. It's your o2.

    By the way - a cheap way to test is to disconnect your o2 sensor harness (no need to pull the o2, just disconnect the harness) and drive around. If it stops kicking, there's your problem.

    Also, change that shitty FMU out unless you feel like looking for a new engine soon. It's probably your poor af ratio thats killing the o2 prematurely.

    injectors might need to be swapped out.
    190cc is a little small for 8psi IMO.
