Assuming that you have some way of tuning the ECU or at least looking at the long & short term fuel trims before and after the mod you should be able to tell approximately how much bigger they are and adjust for them. Using a larger diameter intake pipe where the MAF sensor measures airflow may be one way to account for them if full access to the ECU is a problem. From what I've read the stock injectors are maxxed out with basic mods on the 2.0T so anywhere between 400-500cc is about the size you currently have but that is just an estimate on my part. Try some digging on the various forums and google searches to see if anyone has flow tested them. You may also want to upgrade the fuel pump as well if you are upgrading the turbo at some point.
