At Slayer Performance, excellence isn’t our goal — it’s our standard. We are a team of professionally trained tuners from Hennessey Performance, driven by an unrelenting pursuit of greatness. Every build, every calibration, and every innovation reflects our obsession with pushing limits and redefining performance.

We work a deliberately narrow list of platforms — BMW, Chevrolet, Ford and Dodge — because depth beats breadth. Knowing eight engines properly is worth more to you than a shop that claims two hundred and has seen yours twice.

Every calibration is written against your car's own data. We log the vehicle in front of us, work to what the hardware can actually deliver, and verify it under load before it leaves the shop. No shared files, no generic maps, no hoping a canned tune suits your fuel and your climate.

We don't just build faster cars. We build cars that stay right — calibrated for how you actually drive, and backed by revisions when your setup changes.

At Slayer Performance, we’re not following trends. We’re creating the next era of performance.
