In short

What you willfind here

This blog gathers the technical guides of Bernis Factory, a car tuning workshop based in Signes, in the Var. Every article starts from a real customer question: what a custom map actually changes, what stages 1, 2 and 3 cover, how to prepare a car before a track day at Le Castellet.

The articles are written by the workshop, with no unrealistic figures: expected gains, mechanical limits, precautions and maintenance after tuning. Three families of topics stand out — engine and electronics, track use, restoration of youngtimers and classic cars.
