This Camaro was a BEAST on the dyno Underground Autosports Inc.

Behind every pull: data, attention to detail, and a passion for getting it right. Because great performance is about how your car drives, responds, and delivers when you get behind the wheel.

Performance experience is a **big plus**, especially with LS/LT, Gen III , Mopar , Modified Vehicles, and Aftermarket Components—but we’re willing to talk to the right technician with a strong mechanical foundation.

We have a busy shop, some seriously cool projects, an in-house dyno, custom fabrication, performance tuning, and plenty of opportunity for someone who wants to grow their skills.

This 2014 Jeep SRT8 didn't just show up for a supercharger and hope for the best.
The owner did what many people skip—he built the foundation first.

The result?
A brutally responsive, hard-charging that pulls with authority from the moment you touch the throttle. The combination of the cam, head work, and transformed this into an absolute monster.
