Well..........Help us understand.

Did you expect the PCM to compensate for new ones?

It won't. If the size of fuel injectors are changed, then there has to be an updated PCM turn.

How do I get the PCM updated? Will Ford do this?

How do I get the PCM updated?

Usually with a hand held turner. Mail order tune.

Will Ford do this?

What model year Mustang are we dealing with? Do you think that that Ford will help you modify your Mustang?
