Awesome

Love it just rev limiter to 4k rpms

Easy to do and love the results!

Jackal is awesome. The car is so much faster now on stage 1.

That’s exactly what my A6 was missing.
Previous car was B8.5 S4 on stage2 single pulley from 034. Nothing wrong with. Sometimes even scared)).
But Jackal tune… I’m going in 👍🏻
Thanks Matt for great job!!!

Top tier customer support.

Very satisfied with the tune and customer service would recommend highly

Kit came quickly and well packaged

Overall everything feels great. Pulls hard even top end. Had a stage 2+ 15 s4 and it didn’t feel like it pulled this hard top end. 1100 miles in on this tune so far. Also gas mpg is still great

Great product, recieved exactly as i expected

Great kit, saved me some money on buying individuals through a dealer. The Tstat is awesome

Very nice and aesthetic badge and it looks awesome on the car! 100% recommend.

100% worth it, this tune really wakes up the car. Matt is amazing to deal with, fast to respond and went the extra mile to help me get set up. Don't waste your time going anywhere else.
