Another beauty in the workshop this week — this jaw-dropping BMW M4 Competition, finished in the incredible San Marino Blue, stopped by Whifbitz for a full check over and dyno power run.
This particular M4 is already sporting some performance mods which were already fitted to the car:
- Intake Kit
- Custom MHD Map
- MTC Motorsport Chargepipes
- Catless Downpipes
- Modified Stock Exhaust
After checking everything over, we ran it on our Dynojet 4WD dyno, and the car put down 468whp, which roughly equates to 543bhp at the crank.
Whether it’s a stock car health check or a fully built monster, we specialise in the BMW M4/M3 so if you need yours tuning or just maintenance please get in touch.
