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.
Supported ECU(s): MED17
