The factory ECU can control the solenoid, so can a replacement EBC.

If you are having trouble holding boost pressure, it could be the controller, solenoid, wastegate, or pressure relief valve (BOV).

Replace the solenoid and adjust your tune. If that makes the difference, then you are done. The next least expensive thing would be to swap BOVs with someone. If that helps, then you may need to crush the diaphram a bit on yours, or replace it.

Find the problem, then apply the solution.

Ok, so you have eliminated two of those four, and have a replacement for the third. See if you can make the stock controller do what you want. If not, then ask yourself how much money do you have, what do you want it to do, and would that money be better used on you or on your car.

The error code was something about wastegate A, high input... any ideas?
Happens @ high RPMS and >= 22 PSI of boost.

Note1: Car actually felt like it had a bigger turbo in it, but something is up obviously.

Looks like you're over boosting... and even worse, you are running extremely lean while doing it. The reason it feels faster is because you are so lean. You probably are making more power, but at the expense of your engine. It's good that your car was throwing a CEL. It was letting you know that something is/was wrong.

Notice the last half where you are running 20+lbs of boost and 14:1 AFR's? That is extremely dangerous. Did you hear a sound that sounded like BB's being dropped in a can or anything else unusual?

I gotta tell you man; you built the car up, had it tuned and should have left it, as when I drove it, it was feeling great. Now that things have changed on it, you are running around with what looks like an unsafe tune and running a huge risk of blowing your engine.

If things are sorted out according to you (the smell of gas etc. is gone), then I would get it retuned and be happy with it. I smell all kinds of things every day from my car, it's the price of running a built engine and large turbo.
