Is it necessary to have a tune-up after installing a fuel injector?

Its not necessary to tune up the engine after the fuel injectors are replaced. It is necessary to replace all the fuel injector seals and I would suggest replacing the fuel filter at this time as well. It is a 2.5 to 3 hour job to replace the fuel injectors and the spark plugs are in the vicinity if they haven't been changed lately perhaps it may slightly reduce labor costs to replace the plugs now as oppressed to replacing them in a few thousand miles.
