A4 b9.5 tune questions

I’ve recently been looking to tune my 2022 audi a4-45 premium plus. My first idea was to go to the big names such as IE as i’ve heard promising results from them. The problem is, they don’t have tuning available for the 2021+ a4s yet. I decided to do some further research and discovered the jb4. Does anyone have any experience and are willing to share their results with the jb4? Does anyone have any other brand recommendations? Help would be greatly appreciated!
