Its running l8 msd closed loop groupa coil standard distributer set up with ngk bcr8es at .7 mm i think and ive not done afr yet and what sensor controls the fueling below 3500 rpm if any thanks

 

If it has big cams and or a big port head it may not like closed loop, Is the coil lead running close to the mapsensor,
If it is just a off the self chip it may be best to get it live mapped to get the best drivabilty.
