You can try and see how it runs after changing the injector size

I was able to get it started, however engine seems like it wants to stall when throttle is opened a little bit. Then it seems ok and starts to bog as throttle is opened more. I calibrated the TPS and updated the fuel injector setting. I'm also using a Adj Paxton fuel pressure regulator. Fuel pressure set to 45psi (vacuum line unplugged).
Any suggestions?

Post a datalog capturing the issue you are having. Also, make sure the datalog is logging the wideband data.

So I'm a little new at this when it comes to the S300 and forced induction setups. I'm using a stock o2 sensor. Do I need to replace that with a Wideband o2 sensor?

You install a wideband to be able to read the Air fuel ratio. This allows you to dial in the air fuel ratio.
