OE Tuning helps create the world's most powerful supercharged E46 S54 M3 - 610 whp
610rwhp 423lbs torque for a VF Stage 3 M3 tuned by OE Tuning is now the world's most powerful supercharged S54. The vehicle was previously running a tune from VF's partner, GIAC, but there were concerns about the car running too lean as well as having idle surge issues which are well documented with VF cars. OE Tuning managed huge gains as well as a safer air fuel ratio from the previous tune.
Here is how the car looked with the previous tune:
Congratulation to OE Tuning and car's owner, CarbonChooch.
