Fixed my fuel stumble

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.

Works great

Since I never noticed much of a fueling issue before I have to defer to my tuner. He had no issues and recommended that I get this kit. Works like it should and car is happy.
