Audi A4,
woken right up.
The A4 does 'quietly competent executive' brilliantly, but underneath the tasteful trim it's a proper VAG tuning favourite crying out for more. We'll turn up at your place with genuine kit, dial in that TDI torque or TFSI pace, and back up your original file so you can undo it whenever you like — not that you will.
Typical Stage 1–2 gains — up to
bhp
Nm torque
Estimated peak gain across A4 engines. Your car's figures depend on spec, year, fuel & condition — we quote honest numbers, never fantasy dyno bragging.
So, what's in it for your A4?
Audi ships the A4 detuned, and that's not a conspiracy — it's just easier to sell one softened ECU map across every country, fuel quality and neglected service schedule on Earth. Which means your B8 or B9, whether it's the 2.0 TDI or the 2.0 TFSI, is quietly sitting on a chunk of performance it's never been allowed to use. VAG platforms are a tuner's favourite for exactly this reason.
A remap hands that headroom back. On the TDI it's a proper slug of mid-range torque — the A4 stops feeling politely restrained and starts pulling like it means it, with the bonus that an easier throttle can improve MPG. On the TFSI it's cleaner, harder power and the kind of pace that makes the badge feel earned. We come to you, plug in genuine dealer-level tools on a stable power supply, and get it done without you ever seeing a waiting room.
Your original map is backed up before we start, so it's fully reversible, no drama. DPF, EGR and AdBlue are left completely intact and road-legal. And we deal in honest estimates, not fantasy figures — what you actually gain comes down to year, spec, fuel and the condition of the car, so that's what we'll tell you.
The numbers (the fun part)
Standard vs remapped, per engine. Bars are scaled to peak bhp — the red is what you've been missing.
B8 2.0 TDI (~143–177 bhp)
B9 2.0 TDI (~150–190 bhp)
B8 2.0 TFSI (~211 bhp, EA888)
Stage 1: ≈ 260 bhp / ≈ 400 Nm · Stage 2 shown (needs supporting hardware)
B9 2.0 TFSI (~245 bhp, EA888)
Stage 1: ≈ 300 bhp / ≈ 430 Nm · Stage 2 shown (needs supporting hardware)
Typical estimates for a healthy vehicle. Stage 2 needs supporting hardware (intake/exhaust/intercooler) — we'll only suggest it if your car's up for it.

What's in the box
The small print (yeah, yeah): always tell your insurer about a remap — it's a mod, and "forgetting" can sink a claim. If your A4 is still under manufacturer warranty, a remap can affect powertrain cover, so weigh it up first. We keep your original file backed up either way.
Questions you're about to ask
Should I declare an A4 remap to my insurance company?
Yes. A remap is a modification and must be declared, or you risk your policy being invalidated after a claim. Because we back up your factory file before writing anything, the A4 can be returned to completely standard whenever you need it for insurance, warranty or resale.
Does a petrol TFSI or diesel TDI respond better to a remap?
Both respond well, but differently. The 2.0 TFSI petrol gives strong, eager power gains and feels genuinely quicker, while the 2.0 TDI diesel delivers its biggest gains as mid-range torque for effortless overtaking and towing. We'll tailor the map to how you actually drive.
Will the remap keep my A4's emissions equipment intact?
Yes. Our performance and economy maps keep the DPF, EGR and all emissions hardware fully functional — we never delete or disable it. Your A4 stays road-legal, MOT-ready and clean, just with the extra performance unlocked.
