2020 BMW M4 Power Upgrade at Whifbitz

/ by

This week we had the pleasure of working on a truly stunning San Marino Blue 2020 BMW M4 in the Whifbitz workshop. Already an eye-catching machine thanks to its incredible paintwork, this M4 now has the performance to match its looks.

Upgrades Installed

  • VRSF Single Midpipe – improving exhaust flow and sound.
  • ECU Bench Unlock – unlocking so we can remap the ecu.
  • Bootmod3 Stage 1 OTS Map – ecu remap giving big power gains.
  • FTP Motorsport Chargepipes – ensuring strength and reliability under increased boost pressure.

Dyno Results

With everything installed, the M4 went onto our dyno for a full power run. Running on 99 RON fuel, the car produced an impressive 560bhp.

The combination of upgrades transformed this San Marino Blue M4 into a serious performer – sharper throttle response, stronger midrange, and a harder pull at the top end, all while maintaining everyday reliability and usability.
