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, B7 RS4, and B8-S5 4.2L has shown, our software has been proven time and time again to deliver real world performance. That continues with our tuning for the B8-RS5 4.2L FSI V8. We purchased our in-house B8-RS5 4.2L in mid-2017 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-RS5 4.2L FSI V8!

Why is our tuning the BEST? Our Stage 1 performance software is specifically designed to maximize the engine power output capabilities with stock transmission software.  Following our success with the B7-RS4 and B8-S5 4.2L FSI Performance Software, we began extensive research and testing with our in house B8-RS5 4.2L. Our tuning will give your RS5 improved throttle response and more power throughout the entire RPM range leading to faster acceleration and a much more rewarding and refined driving dynamic.   

Performance:

Our preliminary testing we have shown exceptional results of 11.9@114mph on 91 Octane!

Benefits:

In addition to optimal performance,  our JHM Stage 1 Performance Software significantly improves the RS5s EGT (Exhaust Gas Temperature).  This is beneficial because lower EGTs will improve catalyst life, and better engine protection for long periods of hard use for Road Racing, Autocross, Etc..
