DOS TUNE – Precision. Power. Performance.
Since 2006, Abdullah Al-Dosari, founder of DOS TUNE, has specialized in unlocking the true potential of performance cars. With nearly two decades of hands-on tuning experience, he is known for delivering safe, reliable, and powerful calibrations for both street and race builds.
Our focus is on American performance cars with GM engines such as LT1, LT2, LT4 and the LS, to Ford Coyotes and Dodge HEMIs, while also offering expert support for Japanese and European vehicles. Whether it’s a daily-driven street car or a 2000+ HP race build, every calibration is tailored with precision.
At DOS TUNE, tuning is more than just flashing files, every calibration is data-driven, tested, and refined to match your exact setup. From optimizing cooling systems and dialing in ethanol blends, to fine-tuning standalone ECUs like MaxxECU, our goal is simple: power you can trust, results you can feel.
Over the years, Abdullah Al-Dosari has tuned everything from 200 HP street cars to record-breaking Corvettes and championship-winning builds. Enthusiasts and racers across the GCC and beyond choose DOS TUNE because it combines proven results with a tuning philosophy built on precision, performance, and safety.
