Anyone have exp with Flash Tune 2017+ r6?

I found a seller on eBay selling a bench tuning kit where you pull the ecu out, hook it up to your computer and upload a map on there. They seem to have a stock map, and a de-restricted map. After looking through the files it looks like the de-restricted map is a bit richer and the timing numbers are slightly different in places. I'm really not looking to pull more timing because I only have the shittiest gas here (91 octane) but id like to add more fuel down low because sometimes it seems like if I go wide open throttle at low rpm i can hear what sounds like detonation or valve noise, so I was thinking it might help if it had more fuel or less timing down there. The bike is stock except a cat delete. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/eufabx/anyone_have_exp_with_flash_tune_2017_r6/?utm_source=ifttt
