Fitment is read from the ECU part numbers in our own database, not from a generic catalogue. The same engine and control unit are fitted to several cars, which is why one page serves them all.

Measured here, tunable everywhere

The figures in the table above are readings taken on the dyno for this engine, not software estimates rounded up to sell a file, and our Stage 1 is calibrated to stay inside the margins the engine was designed with. Only a part of our work is published this way: every ECU, engine and model we can read can be remapped for power, measured page or not.
