what did u set the co to at idle?

 

5 turns clockwise and then 1.5 turns anti clockwise

 

no, what CO in % at idle?
and did you have lamda sensor connected to ecu for cloosed loop working?

 

yes offcource i do that

 

should be around 0.90% at idle

make sure all base settings are correct, ie fuel pressure etc etc, and make 100% sure you have NO air leaks.

 

Why ask here? Why not ask MSD, they are very helpfull and offer good customer aftersales advice.

 

As above after sales are excellent.
