Your o2 voltage is off, sensor is probably dead. In the manual, which you should own if you work on your vehicle yourself, there is a procedure to test for restistance values. It will affect your car, as the majority of your car's operation is based off it.

My other question-
I cannot get my boost any lower than 14-15 psi. I dont know why. I made a custom boost controller. I am 100% sure that everything is hooked up right. Also, my Injector d/c is maxed out to 105%. I need to lower my boost! I have a 3/S fuel pump in my car, I was wondering if this was causing me to not boost any lower than 14-15 psi.

The fuel pump size should not MAKE YOU run a amount of boost. If its way oversized, it could mess up your tune and the ability to tune, but running xxx fuel pump doesn't automatically make the car run xxx amount of boost. They are not directly connected to each other in that way. They are components of seperate systems, that are interconnected in your vehicle, which eventually connecting to your motor. I had a 3kgt pump in my auto, running 11psi of boost off the factory bcs...everything was gravy. Your boost controller is sticking and failing. Too stiff of a spring? Sticky ball? Kinked line? Something is out of whack. Maybe your wastegate actuator is bad?

Well the mod list is on my signature. Can you guys tell me whats wrong? I've ran out of ideas.

Yes. See above. Also, running open downpipe isn't the most effective way of making power on a street car.
With the stated 1/4 time, either your car has severe tune issues, or you need to drive the car in a different manner.
Good luck.
