    Question Seems like no boost

    Hey. My 2004 WRX went to safe mode, check engine on. Showed that its MAF sensor. Exchanged myself. Now its running over 4000 rpm's but still has no kick as it used to have. Is my turbo down? Not showing any codes now. Purchased ScanGaugeII and here are some readings on neutral, stopped, engine running:

    FIA: 35'C
    IGN: 9 to 12
    MAP: 5,7 to 6,3
    LOD: 1

    Anyone got an idea what the numbers should look like?

    Car has got 5MT, K&N Cold Air Intake (in the fender) HKS Air Power Muffler, apart from that it seems stock.

    Please help!

    Thanks.

    I may make an idiot of myself but did not find it. Please note that I have absolutely no idea what does that mean. English is my second language btw.

    Found some other numbers:
    Loop Closed
    RPM: 680-747
    TPS: 10
    WT: 90'C
    TFC: 0,12
    CPK: 9999
    VLT: 13,8

    Some of these are not in a manual or I'm just blind :P

    Those codes all have to do with your intake system. I would remove the K&N intake and replace with the stock intake. For your reference: Intake FAQ: Read if you are thinking of buying one! - NASIOC

    Thanks. Only thing that really bothers me is that it happened around 2-3 weeks after exchange. There was a cone installed already and it was running good but I have exchanged it. Did it maybe one week after I purchased the car. Put in K&N as old one was dirty (car comes from Texas). Should not it occur immediately after exchange? I do not have stock filter housing.

    Did a re-set of the ECU and seems to be OK. No errors. Boost is back. Just not as nice as it used to be. Thanks for tips lads. Take Care.

    I would check the intake tubing for leaks or you might be back in the same boat
