We have specialized in tuning naturally aspirated (NA) or "all motor" 4.2L V8 engines since we started tuning the B6-S4 in 2008. Ever since then we have been the number one company when it comes to Audi V8 performance. Like our success with the B6-B7 S4 and B7 RS4 has shown, our software has been proven time and time again to deliver real world performance. That continues with our tuning for the B8-S5 4.2L FSI V8. We purchased our in-house B8-S5 4.2L in mid-2013 and immediately began developing software. After countless revisions and putting the vehicle through our rigorous R&D process, we are happy to now offer the ultimate performance software for your B8-S5 4.2L FSI V8!
In true JHM fashion, here is some footage of our in-house, record setting B8-S5 running 12.6 seconds at 108 mph in the quarter mile!
Not only does our software perform, but it performs time and time again. Here are three back-to-back 12 second passes:
JHM Performance Software for the B8-S5 4.2L FSI V8 will completely change the dynamics of how your S5 performs. This is because we change hundreds of ECU parameters to extract as much power possible and doing so without removing OEM safety parameters. You will experience much more torque throughout the entire RPM range and notice how much more powerful the car is when coming out of shifts. Not to mention our famous Launch Assist feature will help you execute a consistent launch each and every time. Our software turns your car into something that the S5 should have been from the factory.
RECOMMENDED SUPPORTING MODIFICATIONS
Our software alone will completely transform your S5. However, if you are looking to extract even more power, here are a coupe modifications we highly recommend!
- JHM 2.5" Cat-Back Exhaust System: The 2.5" exhaust system that we offer for the B8-S5 will allow the exhaust to flow more efficiently with the calculated scavenging effect of our X-Pipe, allowing you to make more power.
Please go back one section to take a look at the product pages for the above recommended supporting modifications.
NOTE FOR MODEL YEAR 2008
The LATE style Oil Level Sender is needed for model year 2008 S5s only. This is because our software updates you to a newer software version that was not made available to the 2008 vehicles. By not having the updated Oil Level Sender, your car will display an "Oil Over Filled" warning. This will not affect the car in any way and will only be an annoyance until the oil level sender is replaced with the late style. A good time to change the Oil Level Sender is while doing an oil change since removing the sender will cause you to lose some oil. We have both LATE Oil Level Senders and Oil Change Kits available in our store if you go back one section!
One of the benefits of having the LATE Oil Level Sensor is that you can reprogram your MMI to utilize the new sensor's ability to display your current oil level!
Check out our write-up on how to reprogram your MMI HERE --> MMI Oil Level Display for 2008 S5.

- It's not going to blow your mind away, but it'll make you love the car more, for sure. It makes the car more responsive to throttle inputs, especially right after shifts. It definitely adds some power across basically the whole RPM range, but it feels extra aggressive over 3,000 RPM's. It's quieter at cruising speeds, but just as loud at WOT. I swear it also almost sounds deeper in pitch now, as well as having burble off-throttle for DAYS. I'd strongly recommend it to anyone looking to get the most out of their car. (Posted on 4/10/2020)
- A Worthy Tune
I purchased a used 2009 S5 end of summer. It had the AWE track exhaust installed by previous owner. My birthday was Mid Nov and said I'd drive her like she was and get a tune for my birthday. I just got around to it, and she definitely runs different, and in all good ways! It might be the throttle response that is so much different that is the large majority of the difference, but she just seems to run netter overall. My friend described it best. It's like she got over her cold.
The only possible negative is why I mentioned the AWE exhaust. The exhuast isn't quite as growly, and it's much quieter when just cruising.
I have a stick and I have to relearn how to shift with this new tune the throttle reslonse is so much more sensitive.
I highly recommend this product. It is a bit of a different car with it installed. (Posted on 11/25/2017)
I drove a factory stock V8 S5 for 15,000 miles. Got very used to the car, how it felt, how fast it was, etc. Then I got the JHM Full Exhaust and tune. As they state on their product page, it totally transforms the car. It's more powerful, idles smoother, pulls more eagerly from low RPM, and absolutely ROCKETS forward from 3500RPM. Hard to believe it's still all motor when you hit that sweet spot. You'd swear a turbo has been strapped on but nope, that's JHM for you. Oh and did I mention the sound of the exhaust is absolutely to die for.
Next up is catless test pipes and clutch/flywheel. Can't wait to feel the difference of another round of JHM! (Posted on 12/21/2015)
