If you add larger port fuel injectors without a tune:
- the ecu will attempt to compensate for the over fueled condition that will exist any time the Port injectors are running with the long and short term fuel trims.
- if the ecu maxes out the fuel trims you will throw a system too rich code
If you add larger port fuel injectors with a good tune:
- you will add a little bit of peak power production head room since you will effectively reduce the duty cycle of the port injectors
- you will be wasting your money if you are not running enough mods to need the additional fueling capacity larger injectors will provide (for example a turbo or stg 2 super charger kit)
In short, don't bother until your tuner tells you that you need them and then ask them specifically why you need them. If they can't explain it you then go to another tuner.
