WhatsApp STX TuningTuning the G8x M3 and M4
G80/G81 M3 and G82/G83 M4 models use the S58 twin turbocharged straight six. Standard, Competition and Competition xDrive versions are listed separately because their factory outputs differ.
Gearbox type matters on these cars, so tell us whether yours is manual, DCT or automatic and whether anything has already been changed.
- Is a G80 M3 tuned the same as an F80?
- No. The S55 and S58 engines use different ECUs and calibrations.
- Do Competition models have their own page?
- Yes. Their factory outputs differ, so each has its own figures and price.
