I bought a C&L MAF calibrated for 24# injectors. I thought I had 24# injectors, come to find out they are 21# injectors. Is this going to be a problem? I am trying to lean out my mixture w/ out going back to stock injectors. Any tips?
Who told you that you have 21# injectors? Never heard of those on a Mustang applications. 19# perhaps? (19# is stock on a 96 GT). If it is 19# you just need to order the correct sample tube from Lee at C&L.
