Well, a problem injector decided to really let go today and it sucked. So, I'm going to have them rebuilt and modified for slightly larger size. Mine are stock 26lbs and have always been on high duty cycle at WOT because my motor is a H&C. After talking to John at Injectors Plus, we decided on 32lbs. My question is, if I just swap out the current stock for these slightly larger would I need to retune or is it within a range the computer will relearn and adjust fuel trim using O2 data?
