Custom-written engine files for cars, trucks, tractors, bikes, boats and machines. Pick your vehicle below and see exactly what your engine has been sitting on.
Four choices. Real figures from files we have already written. Every curve below comes from logged road data, not a brochure.
We recommend the stage your hardware can actually handle. Never further. Hover a stage to see what it asks of the car.
Indicative figures, varying by engine, hardware and condition. Every file is written for your specific ECU and validated on logged road runs before handover.
Every file we release is logged on the road — full-load pulls, timing, boost, lambda, EGT — before and after. You get the numbers your car made in your conditions, and a written report to keep.
We read the vehicle, check for faults, and recommend the stage your hardware can actually carry. Free, no hidden fees.
Your factory file is read and archived before any work starts. Reversibility guaranteed in writing.
We write the file for your ECU, then log full-load runs on the road and adjust until the numbers are safe and repeatable.
Written report, before-and-after figures and a named invoice. Plus honest advice on running it in.
Tell us the vehicle and what you want out of it. You get a fixed quote, a slot, and an honest answer about which stage your hardware can carry.
