What Powers the Underground

At P1 Underground Tuning, we’re not just another tuning shop—we’re a movement built by enthusiasts, for enthusiasts. From the street to the strip, our mission is simple: extract every ounce of performance from modern Ford platforms while delivering the reliability and drivability you expect.

 What We Do

We specialize in custom calibration for 2011+ Mustangs, F-150s, and other late-model Ford vehicles—from Coyote V8s to Ecoboost platforms. Whether you're adding a cold air intake or building a boosted monster on E85, our tuning solutions are built to match your setup, your goals, and your driving style.

• Expert custom tuning using SCT, HP Tuners, PCMTec, and Cobb

• E85 conversions, flex fuel tuning, and boosted applications

• Remote tuning with real-time datalog support
