Alfa Romeo Stelvio 2.0 TB – 298bhp!

This MY2019 Stelvio came in for our custom ECU and TCU software. Its 2.0 GME T4 produced a healthy 218bhp on our dyno before tuning. After our Stage 1 tune, it made 298bhp and 350lbft — gains of 80bhp and 80lbft.

The 200hp version has plenty of headroom, and the extra torque should make a real difference on the road.

Before: 218bhp & 270lbft
Celtic Stage 1: 298bhp & 350lbft
