    fitted top-hat now problems

    i fitted a top-hat and boost pipe to my zaf gsi yesterday, when i have drove it today it wont boost at all, eml came on and it went into limp mode, then it wouldnt go past 20mph, pulled over and left car turned off for a while, it run again but still wouldnt boost, put it on diagnostics and came up with lambda sensor fault. has any one had this problem before? will i need a new lambda sensor or could it be something else? car run fine before fitting top-hat.

    if you didnt plug the sensor back in, this is whats caused it, as the boost pipe should cause this problem
