where do i start em she misfires in mid boost and only mid boost, there is a leak where the clutch cable meets the box which is causing the clutch to slip during boost (if i drive for about 70-80 miles its like it dries out and the chutch is good again?), i got it about a month ago and was told it has wrx heads and an sti bottom end and turbo back so it might need to be mapped? .There is a small leak from a bottom bolt on the driver side head....... just general heart break if it was 1 or 2 things i would do it myself any ideas as to who would look at it for me?
