Did APR Stage 1 tune today on my GTI

Lots of bad/wrong information floating around on this thread. I thought I'd reach out to the source at APR to get clarity. The fuel trims do reset, however it's within a few minutes on the first drive. Doesn't take days/several hundred miles as people are suggesting.

Jay is right. I noticed the difference within a couple miles. Basically right away.

Myself as well, left the shop and went and blew a plug out. Not really, but did kill an old coil pack.
I assume the same would be for any stage tune like going 2+
I was a lot more inclined to push the stage one right out of the shop then 2+
