Do you work on the AMG versions?
Yes, the 5.5 AMG V8 biturbo and the 6.2 V8 are present in our catalogue and account for much of the Stage 2 work.
What approach suits a flagship roadster?
Smooth, effortless delivery rather than aggression, while making the most of the headroom the forced-induction units offer.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a vehicle of this value.
