no,i dont want it,but the previous owner made full sh*** on my car,
and i dont know why it is to rich on boost and made no good power.

could wrong cam timing made it to rich/inefficient ?

the car runs fine with a msd chip on greys,but once it made boost it goes rich.
the more boost i drive,the richer it gets.
( afr 11,5 on 1bar boost and 10,0 on 1,7bar)

and it made no more power on higher boost.

perhaps someone could help me,i tried really everything !!

best regards chris
