A friend of mine is having some problems with his S2. Its been in storage for a while but was fine last time it was out.
The problem seems to be, we think its overfueling- black smoke n realy sooty exhaust. Its no where near what power it seems very hesitant to rev and once it gets to say 3k + when i should be coming on boost its just nothing,no power at all, holds back,wont rev.

Can Anyone Help out?

sounds like it has gone into limp home mode. Try pulling the Moteur fuses out of fuse box for a min then try again then. It could have a huge boost leak causing the problem or dodgy MAF.
