    There was some kind of option in the software that showed knocksensor (i guess correction?). but it only showed on/off. And it was reading "off" all the time.
    It is too fast to see on/off unless you can log the sum of the sensor. It is more important if the car is pulling timing or not. The IAM may be down (which pulls timing and eventually boost) or it may be pulling it out of knock correction. Still shouldn't feel NA though and you should hear something if it is that bad.

    Maybe you just got used to the power level of the car - is there a NA impreza you could take a ride in?

    Alright, hehe i had a Corvette C5 before this one for 2 years, and didnt get used to the power in that one i doubt i have got used to it, atleast i hope i havent!

    Called a friend 1 min ago and he will bring is -98 impreza gt wich is running 1.0 bar stable boost. So we will put my boost gauge in his car and se if we get the same reading as his gauge. Will get back in 30 mins

    If it reads the same it still could be a leak in the connections etc. if you only swap the gauge itself.
