I want to give you some advice, and I think you should follow it. You are down in a pit of problems, and I think what I want to tell you will get you most of the way out.

Passing emissions and getting the car running properly are actually 2 separate problems. The first on your list should be passing emissions.

To pass emissions, you need to disable the turbo. The simplest way to do this is to ziptie the wastegate open. Once the wastegate is all the way open, then next step is to put the original fuel injectors back in. After the injectors are in, the last step is to remove all of the Greddy electronics, which means everything except what came with the car.

Once the car is running on original parts again, the ECU needs to be reset, and the car driven around normally for about an hour or so. It is absolutely crucial that you keep the car under 20% throttle, and always below 4k RPMs. This will get the driving cycle complete, and hopefully you will always stay in closed loop.

Assuming there aren't any codes thrown, you can get inspected at this point. You should pass.

At this point, you should keep driving the car this way until you can get tuned. If I were you, I would definitely get Neptune. When you go to the tuner, bring the larger injectors that you removed (or buy ones which match your power level, see the injector calculator in the FAQ). I don't know whether Neptune comes with the ECU at the tuner, but you can work that out when you call your Neptune guy.

This plan should get the car on the road again. You don't want to wait too long to get your car inspected.
