Raven Works in Maple Grove does injector cleaning and they will tell you what they flowed afterwards as well. I probably wouldn't go that route though unless you absolutely couldn't figure out what size they were.

You'll also need something to control those bigger injectors like everybody said. If you plan on keep modding the car I would go with DSMLink. I would also take it over to Shane at DB Performance and have him tune it so you can get the most out of the car as safely as possible.
