Stage 1 remap figures
A Stage 1 remap is a software-only change to the ECU on an otherwise standard car. It needs no extra parts, which makes it the usual starting point.

Who is the Stage 1 map for?
- Drivers who want a noticeably quicker car from a software-only change, with no new parts.
- Daily drivers who want stronger mid-range pull and a sharper throttle.
- Anyone who wants the biggest gain we list without fitting hardware.
What this means for your A5
On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.
Engine management is by a Continental Simos 19.7 unit. Newer ECUs often protect their software, so we read the exact unit and version on the car before confirming the figures on this page.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.

Stage 1 questions
How much power does the Stage 1 map give the Audi A5 45 TFSi MHEV 261bhp?
We expect 325bhp and 499Nm against 261bhp and 370Nm as standard: up to +64bhp and +129Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.
Does a Stage 1 remap need any extra parts on the Audi A5 45 TFSi MHEV 261bhp?
No. Stage 1 is a software-only change to the ECU on an otherwise standard car.
Is there a gentler map than Stage 1 for this engine?
Yes, two. Stage 1 Eco is performance with economy in mind: 309bhp and 489Nm expected. The Eco map is economy first: 304bhp and 482Nm. Both still sit above the standard 261bhp and 370Nm.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
