McChip-DKR has come up with three different upgrade kits for the Giulia Quadrifoglio. However, it’s the Stage 3 one that you’ll want to pay attention to, as it has taken Alfa Romeo’s sports sedan into supercar territory.

By tuning the turbochargers, remapping the software and upgrading other components, McChip-DKR has obtained an extra 170 PS and 250 Nm of torque. Thus, the 2.9-liter, twin-turbo V6 now produces 680 PS and 850 Nm of torque.

Having a Giulia Quadrifoglio with 10 PS and 90 Nm of torque more than the Ferrari 488 GTB requires spending € 15,589 for the kit, or as much as a new Ford Fiesta or Toyota Yaris in the States. As a bonus, the tuner will remove the speed limiter, allowing the car to max out at 313 km/h, 6 km/h more than the stock model.

At € 7,229, Stage 2 is more affordable and unlocks 610 PS and 800 Nm of torque, whereas Stage 1 costs just € 1,999 and delivers 580 PS and 750 Nm of torque. Both upgrades get the removed V-max limiter and, regardless of which one you go for, McChip promises dyno-testing and individual ECU programming.

Pricing for Alfa Romeo’s BMW M3 and Mercedes-AMG C63 challenger starts at US$ 73,995, before destination, in the U.S., while in Germany, it will set you back € 79,700.
