When i had my turbo SRT-4, I ran RC750 injectors along with a SAFCII and had it tuned to 11.8 to 11.9 air fuel across the board. I ran this setup for almost 4 years without an issue on stock fuel pump. Your best bet is to save up for bigger injectors and buy a used standalone to save you some money. But drive the car easy for now. Running rich is ok but running lean is not ok on the long run.

Do anyone have any stock injectors laying around so I can borrow some to see if the problem is my injectors?

I believe I have found a solution!
With the help of s2000junky and his experiences that he had, all I need to do invest in an AEM wideband UEGO gauge, boost gauge, and vafc to see exactly how my car is running.
Wish me luck guys!

One more thing to keep in mind for optimum reliability and dependability is controlling ignition timing. At your current boost level it not a major concern but something you will need to have control of if you plan on turning up the boost.

One thing that I have learned is if you want to do it right you need to use an AEM, K-Pro, etc. VAFC can only do so much as well as any other piggyback systems, Greddy Emanage Blue/Ultimate, AEM FIC. Like Hiep said they are bandages.
It's a lot of money for a standalone EMS but well worth the investment especially if you're going to up the boost. Standalone EMS is a proven solution, all others solutions you may get lucky and get it right but many will many will not run the way you would like it to. All the money and time spent trying to tune a "piggyback type" system will eventually be close to the cost of a EMS.
Trust me I have experienced this first hand. I had a CTSC S2k boosting at about 11psi using the Greddy Emanage Ultimate I always ran into problems with the tune, multiple trips to the tuner, had others look at it and got no clear solution to where I was guaranteed that I would get a perfect tune. The car kept on "learning" and readjusting things. Eventually I brought the boost down to 7psi running on the FMU with decent AFR.
