Steeda were the first company authorised by Ford to sell ECU calibrations in its dealerships, and our great reputation for "factory plus" style tuning has grown every year over the last near 20 years. Smooth, reliable safe power.
If you want monster numbers, rushed out as fast as possible, then look elsewhere...If you want to rely on companies who knock out a Ford tune before moving onto a Volkswagen tune, then an Audi tune, then a BMW tune, then go right ahead.
But it you want a company who ONLY tunes Ford's and will KEEP tuning them and revisiting the tunes and using the tunes ourselves on a daily basis on both road and track, then you will only want to deal with Steeda. We regard our tunes as the most advanced, safest, most reliable custom tuning available on the market.
Steeda Certified Custom tunes pass our rigorous standards for performance, durability and driveability and have an impeccable safety record. Developed and tested on our in house dyno as well as through hundreds of hours of field testing both on the street and some of the most demanding race tracks in the country, you can be sure our tunes will deliver safe, reliable power.
