This should have been one of the first mods I did to the car. Is a great way to properly and inexpensively improve throttle response and it is yet to stumble on me again since I did this mod!

I installed ID 1050x injectors and an AEM 340 fuel pump on my 2019 STI but didn't install this right away thinking I might not actually need it. Tested everything out on my base map and of course there was a fuel stumble around 3K. I installed this afterwards and the issue was resolved.
