Unleash the Power
Welcome to the ultimate performance database. At Tun-Files, we don’t guess – we calculate based on thousands of dyno-tested files and real-world results. Factory software often restricts an engine’s true capabilities to meet broad emission standards or to artificially segment vehicle models. Our custom ECU and TCU calibrations safely remove these limiters, delivering proven power gains and improved driving dynamics.
Dyno-Tested Accuracy
All power (HP) and torque (NM) figures are backed by extensive dynamometer testing.
Safe Tolerances
We prioritize engine longevity. All modifications stay strictly within the mechanical safety limits of your hardware.
Extra Options
Instantly check the availability of DTC, DPF, EGR, AdBlue off, and Hard Cut Limiters for your specific ECU.
Global Coverage
Comprehensive database including cars, vans, trucks, and agricultural machines.
