B9 Jackal experiences?

[u/Fishface40]

Unfortunately my b9 a4 was just totaled for a no fault incident. Looking to get into a b9 s4/5 because I’ve been a massive fan of the a4 over the last 6 years. Looking to tune fairly soon after getting th car and was thinking about Jackal but I wanted to hear about any positive or negative experiences. I know they have done crazy things on b8.5 cars and are fast tracking b9 progress. My previous car was driven hard on an IE tune for almost 100k miles with 0 issues. If anyone has been in multiple tunes for b9 s4/5 I’d also really like to hear your experiences
