Michael, find a local shop with a bench top injector cleaning and flow testing set up. Number your injectors when you pull them. Scribe the cylinder numbers on the injectors because the cleaning fluid often removes numbers written with a Sharpie. Have them flow test them before and after cleaning, recording each injector's flow rate. Most shops just want to clean them first, they will charge you extra to flow them both ways, but that's the only way you will know. It shouldn't want to run best with air/fuel in the elevens. Mine likes mid twelves. Some like low 13s.
Good luck
