Who We Are
About ToxicTuning
Built By Enthusiasts,
For Enthusiasts
ToxicTuning was founded with one goal: to give everyday drivers access to the same level of professional ECU tuning previously reserved for race teams. We started as an online platform and have grown into one of the world's most trusted independent tuning brands — with authorised dealers across 7 countries worldwide.
Every map we write is built from scratch for your specific vehicle, fuel type, and modification level. We don't use generic files — your car gets a custom calibration that has been dyno-verified and road-tested before we hand it back to you.
We work with petrol and diesel vehicles across all major European, Japanese, and American brands. Whether you drive a daily Volkswagen Golf or a track-prepped BMW M3, we have the tools and experience to make your car perform at its best.
