A Stage 1 remap takes the C8 Audi RS6 and RS7 from 600bhp and 800Nm to around 700bhp and 950Nm on our rolling road. The C7 at 560bhp goes to about 650bhp and 850Nm, and the 605bhp Performance version to the same 650bhp. Further back, the V10 C6 goes from 580 to around 680bhp and the twin-turbo V8 C5 from 450 to about 500bhp. The C8 gains the most in absolute terms, and 150Nm of extra torque is what you feel.
Measured on our Mustang AWD rolling road in Maidstone. Wheel figures, drivetrain loss added for the flywheel numbers.It’s no surprise that the C8 RS6 & RS7 are FAST. With 600HP on tap under your right foot, a 0-60 time of around 3 seconds is easily achievable. In typical Audi fashion, looks and practicality are equally as impressive for such a car. This makes it arguably one of the best all rounders out there! That doesn’t mean that these cars can’t benefit from some JFA RS6/7 C8 Tuning of course!
As many may know, these cars share an identical drivetrain, and therefore both benefit equally from remapping! By far our most popular option would be a JFA Stage 1 remap. This article will explain more about what we do whilst your vehicle is with us, focusing on the black RS7 you see in the pictures below.
Stock Figures
Audi love to downplay the true power of their RS cars especially. Even though 600HP and 800Nm torque from a stock car sounds ridiculous, our dynameter shows this particular RS7 is running a staggering 631HP & 834Nm Torque! This isn’t a shock; we know from experience that German car manufactures like to sell short their figures.
These figures are great and all… However we know that after the map, the results are going to be much greater!
Audi RS6/7 C8 Tuning Figures
You can never have too much power, and no where does this apply more than with the C8 RS6/7. After running diagnostics to ensure every system in the car is healthy, our file writers got to work on the map. The purpose of this is mostly precautionary as any issues prior to mapping could be exaggerated once running a significant increase in torque.
After each major map tweak, the car is run on the dyno to measure it’s performance. These adjustments are what really set JFA apart from the competition.
We eagerly started the final dyno run to find that the the RS7 has been transformed to be run 733.8HP and 1056.9Nm Torque. Needless to say with 256Nm Torque more than what Audi quote from factory, the owner was over the moon – “It feels like an entirely different car!”.
Take It To The Next Level
While the Stage 1 remap is by far the best ‘bang-for-buck’ modification that we recommend, there are still an abundance of modifications that we offer for the C8 platform, notably giving the exhaust a much needed upgrade and a stunning Eventuri Carbon Intake system.
Remus Aftermarket Exhaust System
Our recommended exhaust system for the RS6/7 has to be from Remus Exhausts. They offer both Axleback or GPF Back systems with a variety of tip options to choose from. The GPF Back system offers for a much deeper, louder and more aggressive tone that you’d expect from a RS car, especially a Turbo V8 like this. The Axleback system offers customers a nice middle ground option; a notable increase in sound with much more character than the stock system without compromising cruising volume comfort.
Eventuri Carbon Intake For Audi RS6/7 C8
Eventuri is a company known in the Aftermarket industry for being the best of the best when it comes to intake systems, and the system for the RS6/7 C8 is no exception. Working around the limited space of the car’s engine bay, Eventuri developed this intake with lots of scanning, simulation and real-life testing to ensure their system offers both increased flow rate and smoother air flow. All of this taken into account, Eventuri state that the intake alone amounts to horsepower increases of 45-50HP! Needless to say, it also looks remarkable! Take a look at Eventuri’s site here. This system has just been released and can be ordered through us now – get in touch for a quote!

Questions we get asked
How much power does a C8 RS6 gain?
Around 100bhp and 150Nm at Stage 1: 600 to roughly 700bhp and 800 to 950Nm, on standard hardware. The RS7 uses the same engine and reaches the same figures.
What about the older RS6 generations?
C7 560bhp to around 650bhp and 850Nm, and the 605bhp C7 Performance to the same 650bhp. C6 with the 5.0 V10 from 580 to about 680bhp. C5 with the 4.2 twin-turbo V8 from 450 to around 500bhp, or 480 to 520bhp on the later version.
Should the gearbox be tuned as well?
At 950Nm, yes. These use the ZF 8HP with its own torque limiter, which will clip the engine unless it is raised. We would do both together rather than have you pay for power the gearbox refuses to pass.
Does the particulate filter matter?
The C8 has a petrol particulate filter and it stays. Removing it makes the car illegal on the road and fails its MOT. The file is written to work with it in place.
What does Stage 2 need?
Downpipes with sports cats and usually an intake. Tell us what is fitted or planned and we will write around it and give you a realistic figure before you spend on hardware.
Will it affect my warranty?
A main dealer can detect a remap and may decline an engine or drivetrain claim. We keep your original file and can put the car back to standard before a dealer visit.
