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.

- 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 SL
Turbocharged petrol engines respond well to calibration changes: boost and timing are the main levers, and the result is a flatter, stronger torque curve as well as a higher peak.
Engine management is by a Bosch MED17.7.1 unit. We read the ECU on your car and compare it with the software listed here before any work starts, so you know what to expect before you commit.
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 Mercedes-Benz SL SL63 AMG BiTurbo 537bhp?
We expect 642bhp and 988Nm against 537bhp and 800Nm as standard: up to +105bhp and +188Nm. 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 Mercedes-Benz SL SL63 AMG BiTurbo 537bhp?
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: 616bhp and 973Nm expected. The Eco map is economy first: 607bhp and 964Nm. Both still sit above the standard 537bhp and 800Nm.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
