   Buly,

   Before you make any changes, install a pressure differential system
   to measure the inlet pressure, pressure under the cowl on the
   'downstream' side, and static pressure. Then make a flight and
   record the data . You need to have this as a base line for any
   changes to see if the problem is being made better or worse. Some
   changes that seem 'obvious' have a negative effect. The only way to
   be sure is to make the measurements.
