Well I've been told that unitronic does offer a ko4 file with a 5bar fpr so I have to look for bigger injectors I know my car a 98 a4 1.8t uses an ev6 plug so my questions is can I use a any injector as long as its an ev6? Cuz I know the 99ish buicks that are supercharged use 380cc/36lb injectors and there also an ev6 so can I go that route?

So yea on top of injectors I'm going to need to go back to a stock 4bar or even a 3bar fpr according to what I've read....
