    Tomei fpr and greddy turbo timer questions

    Hey all, I am the proud owner of a 2005 wrx and just a couple questions.

    1. I set my greddy turbo timer at 10 seconds which it usually turns off at that mark but for some reason it will automatically change anywhere from 30 seconds to a minute and a half, has anybody heard of this? It was already on there when I got the car.

    2. My stock fpr is on its way out (fuel smell, stumble between 3500-4500rpm and backfire...a lot and loud!) so I figured I would buy an adjustable one and have decided on a tomei adjustable fpr. I was wondering what pressure to set it to. Below is the list of engine related mods...

    Perrin: fuel rail kit, front mount intercooler, oil catch can
    Greddy: profec spec b2 boost controller, turbo timer, type s bov
    Precision: 16g turbo set at 19psi
    Invidia: catless up/down pipe
    Sti: injectors
    Walbro: 255 fuel pump
    k&n: intake
    Magnaflow: catback exhaust
    NGK: one step colder spark plugs
    Exedy: stage 3 clutch (just thought I would throw this in there if it made a difference)
    Protuned by boostcreep in colorado

    Thanks in advance for any suggestions

    You do not need an adjustable FPR. Just purchase another stock one if you think your is on the way out. Or even better,verfiy that it is the issue by testing the fuel pressure.

    It was tested by subaru and they said that is the problem. I was told by them it will be replaced at no charge because apparently it is somewhat of a common issue in 02-05 wrx's especially in cold weather and there was a recall but then they told me its not free because I have perrin fuel rails and not stock. My mpg as gone waaaay down too. They said they fpr needed to be replaced as well as the fuel lines connected to it and I was leaking fuel.
