If this is in the wrong place, I'm very sorry. This forum is a bit confusing. I am looking for a complete, accurate, defenition file for my 2013 fiat 500 abarth multiair. Usa version. My car is already flashed via powergate. But my files dont allow me to edit things I need for a larger turbo I want to install. Namely injector flow rate or scaling, latency, eliminate p0420 code, and so.e other things like torque over time and stuff. Any help or info would be much appreciated. I'm very new to ECU flashing with stock hardware. I've been installing and tuning haltech for nearly 20 years. Some.of my terms used may be off. I apologise up front and thanks for your time. Cheers!

Marelli 8gxx.
I have hardware number, software number AMD all that if necvessary.
