It's 2022 and i'm wondering the same thing.
The email I used was

I'm trying to see if they know how to get rid of throttle lag on my truck as part of the tune.
When i'm at a stop and I put my foot on the gas say 15% I expect it to move but sometimes it doesn't move and acts like I didn't touch the gas. After 2-3 seconds of not moving my foot it will then engage and I will move, or I can slam it down and it will engage right then.
It's almost like my truck isn't sure if I actually want to move or not very weird and extremely unsafe, I can't count how many people I cut off by mistake as I expected my truck to move and it just sits there and then moves seconds later.
