Couldn't ask for a better product. The Merc Racing Heat Exchanger just works! Jackal Motorsports is top shelf when it comes to Customer support.

It's a cable. It works as expected.

AAA shipping and even better service i had a lot of question and needed some help and Matt answered and help me with everything i needed fast and reliable even through email would highly recommend jackal motorsports to anyone.

I researched quite a bit before deciding who to go with for a tune. I found out about Jackal and after hearing all the hype, I joined the FB community to ask questions and 'get a feel' for what was going on. The community is great, very helpful and informative and the quality of the software was evident from all the feedback. Given that their software is also pretty much the cheapest on the market, it seemed a no-brainer. I'm now stage 1 (also bought plugs and CTS intake all from Jackal) and it's awesome, really wakes the car up - the power increase is aggressive but its delivery is super smooth. The gearbox tune is crisp and very responsive, it really is like driving a new car. I'm VERY happy with it, I find myself smiling walking up to my car!

If you're thinking about it, DO IT, and thank me later!

Initially flashed the stage 1 tune until I installed my dual pulley setup then went with the 2+ dual pulley tune and the low end power combined with the I swear faster than before shifts is a lethal combination .

Incredibly fun!!! I am always excited to get into the car and give it a little gas. Over the year I have made rookie mistakes with upgrading my car (for instance I didn’t buy a new HPFP when installing an upgraded Piston) and every single time Matt is there to take a log and give me some incredible feedback. One of my favorite parts of this company is how easy it is to send over a log and get the information you need within hours. Always responding fast and I see it all over the jackal community, we love this customer support👊. I know I will never change off jackal, and I am very excited for every single future update. The latest update for my model was amazing, and I didn’t think it could get better. I can’t wait to see everything there is to come. Thanks Matt and Tony for an excellent tune, it’ll be on all of my future Audi’s.

Can’t beat the cost, especially coming pregapped for the jackal sauce

This car rips with this Jackal tune. Before them I was running 3.4 0-60 on apr and the Jackal tune brought me down to a 3.1 0-60 (before the upgraded inlets). I’m excited to see what this car will do on some rs (or bigger 🤓) turbos. Would 100% recommend jackal for any 4.0t audi or any audi in general!

As always great products, fast shipping and great customer service

Car has been tuned for a couple of months now. Added trans mount and rear diff bushing. Haven't had decent weather to get a solid launch, yet. Dragy is on damp pavement with touring tires. Totally at home cruising at 80 on the highway or spinning all 4 from a dig. I ran an E30 blend a few times and everything was better, except gas mileage. Oh well. Wife doesn't like driving in Dynamic / S, which means it works. Moves just as fast as my DPE40 B8 S4 without any of the violence. Turn on your speed warning...

Super smooth and fast

thank you to matt for redirecting my lost package so i could get this on time

Really good job on everything, cable, tune and ease of flashing software!
