Petrol · 4.4 litre · Maidstone, KentWiesmann GT/Roadster MF4 remap367 to 388 bhp with Stage 1 software. The figures, the parts and the other engines in this car, on one page.
A Stage 1 remap takes the Wiesmann GT/Roadster MF4 from 367 to 388 bhp and from 490 to 530 Nm: 21 bhp and 40 Nm more, on standard hardware. On a turbocharged petrol the gain comes from boost, fuelling and ignition timing recalibrated within the limits of the standard turbo and injectors. It is done in a visit at our Maidstone workshop and the original file is kept, so it can go back to standard.
