ok not sure what the stock timing is for the st205? ive been reading alot lately i think im pulling timing thats why my car is idling fine but whenever i push on the gas or try to go somewhere the car will start to backfire and sometime just die. starts to happen about 2k to 3 k rpm? wideband reading is showing me my car is running really rich 10 at idle and while driving underboost it reads really lean 16-17...
so should i advance my timing or retard it??
