About us

AT Tuning is a professional B2B chiptuning file service for auto mechanics and workshops across Europe.

Our model is simple: the mechanic uploads the original ECU file through the web platform, selects the desired chiptuning service (Stage 1, Stage 2, DPF off, EGR off, AdBlue off, and more), pays with credits, and we return the tuned file within 15 to 60 minutes. Guaranteed.

The chiptuning catalog covers over 55 makes and 12,000+ engines with ready Stage 1 and Stage 2 gains, dyno curves, and complete ECU data. Every chiptuning service is automatically mapped to each engine that technically supports it — the mechanic immediately sees what they can order.

The platform is built from the ground up with a focus on security, speed, and simplicity. ECU files are encrypted, every chiptuning job has real-time status tracking, and communication takes place through the integrated chat within each order.
