How are emissions affected with FI?

Does anyone here with a supercharger or turbo live in Maryland? Wondering b/c we have pretty strict emissions testing here, and I was curious as to how passing with FI is. But if you're anywhere that you're required to do emissions, I'm sure you can help some. How is passing with a supercharger or even a turbo setup? How much are your emissions affected? Does the amount of boost you're running make a considerable difference in emissions testing?

It's actually easier to pass emmissions with a blower and you can get away with a little bigger cam than N/A motors.

Really?? Good to know! Why is that? I don't doubt you, I'm actually just curious as to why that is if anyone knows?

Main reason is that the motor is more efficient when it is FI. The compressor is allowing the motor to take in more air then it could as a N/A and if you look at FI motor's efficienies, its normally over 100%.
