What Stage 1 involves

Stage 1 is for a standard car with nothing fitted. We read the original file off the ECU, write a calibration developed for the 3800 344hp (253kW) 1620Nm, then road or rolling road test it before handing the car back. Nothing is added and nothing is removed, so it looks and services exactly as it did.

It takes most of a day. We keep your original file, so it can go back to standard at any point. Figures here are for a healthy 3800 344hp (253kW) 1620Nm, and we check the car over before writing to it.

See the full 3800 344hp (253kW) 1620Nm page for every file and figure, the other engines on this Xerion, or all Claas remapping.

We write and test every file at our Aston workshop, on our own rolling road. Ring us with your reg and we will tell you what your car should make before you commit to anything.
