Right from the start Matt was incredibly helpful answering my million and one questions. This gave me the confidence to take a punt on the stage 1 tune for my 2004 B6 S4. Since then it has totally transformed the car.

It gives far better throttle response and power through the rev range.

The ability to disable the pops/bangs with the cruise control stalk is genius (no cruise features are lost).

I also see around 2 mpg better fuel economy when I am not thrashing it (anyone who owns a b6 knows this is huge).

It was also incredibly easy to flash the tune at home myself and took about 30 minutes total. Having the ability to change between stock and different stages of tunes without additional cost each time is a huge bonus too.

Following the success of the stage 1, I am now going to go all out on a stage 3 package with Jackal including their supporting mods.

If you own a B6 S4, don't wait to flash tune it with Jackal.

Excellent!

2013 Audi Q7 Premium Plus. Im enjoying tune and have no complaints. This tune will not disappoint!! Like a different beast. Shifting improved tremendously with TCU tune aswell. Also my buddy has had tune installed on his Q7 for over a year now with no issues. Thanks Matt.

Had this flashed and omega intake installed. Night and day difference. Shifts are seamless and the low end torque

Had this installed the day I went stage 1. Extremely responsive and an addictive whine comes through.

Awesome, shifting way smoother, much more better top end than previous tuning company, awesome customer service

I love my tune, I immediately felt the power difference. I didn’t think I would feel much since the car is NA, but I was able to install by myself through the simple interface and generate positive results immediately.

Installed the sq5 stage 2+ tune and I was in awe on how reactive my car became. I had stellar customer service from Matt. With all the bolt ons and supporting mods this tune transformed my sq5 into a supercar killer.

Great power jump from stock . Really happy with it . Great service from Matt and team

After installing this tune I was blown away by the throttle response increase, and having the soft limiter removed along with the speed limiter removed was amazing. The burble is absolute obnoxious but I love it anyways. Overall great investment for my S5

Ever feel sad? Well, this Jackal Motorsport tune is the answer. Pure happiness flowing through the veins of your Audi. You’ll fall in love with your car all over again. And to make it even better, it’s reversible and upgradable at no extra cost!

Shout out Jackal!

The heat exchanger came nicely packaged and fit well. Does not come with instructions for installation, but you can youtube other’s installs if you need help. Matt at Jackal let me know right away that the exchanger was on back order, and offfered other more immediate solutions. I opted to wait and he shipped it out as soon as he got it in stock. Great experience and great product.

Love the merc racing HX..always good business with Matt over at jackal I will control supporting them for all my Audi needs 🙏
