The car will start choking after ~2500 rpm. Even if I free rev the engine it wont go pass ~2500rpm. I noticed that the car is running extremely rich. A/F was at ~9.x:1 at idle(was ~14.5:1) and ~10.x:1 when I tried to gas it. I turned off the engine didn’t know whats wrong with it. I let it sit for about 3 mins and started it up again….normal. Revs normal, A/F reads normal. I then drive the car home without any issues.
I suspected the CAS wire because that is the only thing I’ve installed in the past couple of month.
Anyone knows what might be the problem?

I've got 5 bucks on the MAF limp mode. All your symptoms match it word for word. Check the wiring at the MAF for damage. If it happens all you have to do to clear it is turn off the car for 20 seconds then turn it back on.

I will be having the ECU reflashed with the standard reflash that comes with the kit, but I will have GReddy emanage installed and dyno tuned. I will run the stock setup for a month or so for the ECU to settle. Then I will be installing the 440 injectors with the AAM fuel return system and the GReddy EO-1 along with some other goodies...then of course...dyno tune again.
