picking up a speed3 with some issues. First Mazda so hoping to find some good information on here to make fixing it painless as possibly! Thanks

This is what the current owner says.
It’s having a fuel issue and breaks up under boost. I narrowed it down to the injectors. I changed them and it runs worse with the new injectors, it will run for about five seconds very roughly then shut off the issue is fuel related. I think the new injectors I bought are bad it’s getting an injector misfire code.if I get it fixed before it sells the price goes up. since I’ve owned the car, I put a brand new OEM timing kit and ultimate race exhaust with catless downpipe.

If changing the injectors made the issue worse, then it wasn't the injectors to begin with. Ask him who the tuner was, and if he says Dramatune, just walk away; it will probably need a new engine.
