Oh yeah those guys are great; I used them to rework my p2 injectors. They flow 850cc now.
I'm surprised you are bothering with the emanage blue, that thing has had limited success with our car. I am using the cobb accessport to flash tune my turbo 8. Nothing is better for this car right now IMO. Of course if you go this route you will need someone who is experienced with the accessport software for tuning. It's a must to nail down injector scaling and MAF scaling with it.
Kane, who posted above is a flash tuning guru if you have any questions about it. I'm nowhere as near knowledgeable as some of these guys.
