Who in the area cleans and matches fuel injectors?

and Is this worth doing. I heard there can be a wide varience between injector.

Thanks in advance for any input.

 

Try" Kinsler fuel injection systems" out of Troy,Mich,unless there is a problem cleaning and matching (flow rates should be very close to each other)does very little to add power!,over the next 2 tanks of fuel try adding a quality fuel injection cleaner,then change the fuel filter. Like I said unless there is a problem.
