Brand-specific tuning in Signes and around Le Castelet
Bernis Factory is located at 26 Allée de Dublin in Signes, in the Var. This location, right next to the Paul Ricard circuit, shapes our work preparing high-end sports cars and lets us follow your car closely, brand by brand.
Whether you drive on the road, on track or both, we adapt the preparation to the character of your brand while keeping the same standards across our three trades: maintenance, preparation and restoration. The goal stays the same for every car entrusted to us: a coherent, reliable vehicle that remains true to the spirit of its manufacturer.
Why choose brand-specific tuning
Looking for brand-specific tuning means recognising that a BMW M is not set up like a Ferrari, a Mercedes AMG or a Nissan GT-R. Each manufacturer has its own engine architecture, electronic management and mechanical constraints. A generic approach ignores these differences, whereas brand-specific work unlocks the car's potential without distorting its character.
At Bernis Factory, this logic translates into engine and gearbox mapping set individually, by an engine engineer who always starts from the car in front of him. The preparation draws on our full range of services, from engine to braking, and on our closeness to the Paul Ricard circuit, where we support owners every day. It is this combination of brand specialisation and track experience that guides each of our interventions.

Frequently asked questions about brand-specific tuning
What is brand-specific tuning?
It is preparation tailored to the architecture and electronics specific to each manufacturer. Rather than a generic setting, we work specifically according to the brand of your sports car, whether it is a BMW M, a Ferrari, a Mercedes AMG or a Nissan GT-R.
Which brands do you prepare in Signes?
We prepare high-end sports cars, with dedicated pages for BMW M, Ferrari, Mercedes AMG and Nissan GT-R. For another brand, such as Porsche, tell us about your project and we will work out the most suitable preparation together.
Is the mapping different depending on the brand?
Yes. Our engine engineer maps the engine and gearbox case by case, taking the vehicle and its use into account. We never apply the same generic map from one brand to another.
Do you give a price for brand-specific tuning?
No. Every preparation is bespoke and depends on the brand, the model and the intended use. For an estimate suited to your car, the simplest step is to contact us directly.
Do you prepare cars for the Paul Ricard circuit?
Yes. Our workshop is 700 metres from the circuit at Le Castelet. We prepare and support sports cars before, during and after a track day, and we are an official BMW M France partner for track support.
