Opel OPC is the performance division, producing high-output turbo versions. Opel shares platforms with Peugeot, Citroen and DS within Stellantis since 2017. Before 2017, Opel shared platforms with Chevrolet and Buick as part of GM. The Citroen petrol range is shared with Peugeot and Opel within Stellantis. Citroen turbo petrol engines deliver a noticeable gain with Stage 1. PureTech is Citroen's badge for its turbo petrol engines.
On Opel petrol engines, Stage 1 delivers a noticeable gain. Older Opel models (pre-2017) share ECUs with Chevrolet, requiring a different toolset. Within Stellantis, ECUs are standardised, so Opel files (from 2017 on) often work on Peugeot/Citroen. The French Citroen community has a large pool of ready-made Stage files. Mid-range Citroen engines are a mainstream chip tuning subject in Europe.
