As long as your car is getting the proper amount of fuel to keep the AFR where the tuner set it, there would be no benefit. Bigger injectors would still put in the same amount of fuel since your AFR hasn't changed, just at a lower duty cycle. Plus, with larger injectors, you would have to have your tune re-done. I would save the injectors for when you put heads on it.
