i had this installed about a week ago, very nice piece, but it has really caused some problems.
i was told that the ko3 compressor works well with a downpipe, but with software only. Let me tell u what is happening. I lost quite a bit of hp, at wot, the waste gate opens way sooner and bleeds off boost. it has gotten very jerky at wot, like i am getting too much boost, then at about 3500 rpms, the wastgate opens fully and no boost! very dissapointing. i had my ecu vaged and the codes were pointing to too much boost, so i am in limp mode most of the time since i drive the car floored a lot. Please tell me what i should do?
