I pulled the injectors from my NSX the other day and had them cleaned. The guy that cleaned them has done several sets from other cars and motorcycles for me. Before the cleaning I had a noticable vibration on startup and a slightly shakey idle. The injectors were not far off for flow balance but once cleaned all of the little issues cleared up. I did this on my Legend last year. Those injectors had a pre-cleaning flow imbalance of 6.2%. Once cleaned the engine was much smoother and the fuel mileage went up significantly.
