About us

Max En Caisse is a French company based in the region of Haute-Saône (70), near Vesoul (15min drive). Our expertise includes diesel engines with CommonRail injection technology, gasoline engines as well as turbos and turbo mounting and fabrication on various engines.

Certified automotive professionals since 2019, this passion was born much earlier, around 2015-2016. Our thirst to offer high-quality services, involving the customer in the process, whether by keeping him informed at every stage or by proposing adapted solutions, has enabled us to forge strong links with numerous customers and partners in the industry.

Having laid our hands on a wide range of engines and vehicles, both petrol and diesel, vintage, touring and everyday, new and old, we've built up a solid reputation in the automotive industry.

In 2022, welding and fabrication work has been added, with the mastery of TIG and MIG/MAG welding of ferrous metals, machining of parts, and aluminum TIG welding.

At the end of 2023, the creation of customized parts (2D & 3D design, simulations, mock-ups, prototyping, 3D printing, testing and validation processes) was added to our range of services to speed up the completion of our customers' projects.

In 2024, we also began reprogramming, using quality equipment (AutoTuner, Kess & K-Tag) and the advice and help of our partners, whom we appreciate and who help us to fine-tune the mappings to best meet our customers' requirements.

In 2025, we will be developing our own solutions for mounting electronic wastegates in place of pneumatic wastegates, as well as biodegradable, highly effective and low-hazard cleaning products, to offer even more solutions to our customers' problems.
