It just seemed to make sense that black smoke = overfuelling, fuel pump logs look ok, but I'm still running rich on a stock map. If theres too much fuel going in the cylinders, any oil in the cylinders is being washed away by all the excess fuel, so this coud cause black smoke and high oil usage issues??
Ive being phoning PDtuning for the last 3 days trying to get a leakdown test done, but no-one answers the phone!
