Enhance your fuel-injected engine's performance without sacrificing drivability or triggering check engine lights with Comp Cams Computer Controlled Series Cams. Specifically engineered for computer-controlled vehicles, these camshafts optimize power and torque while maintaining compatibility with factory ECU parameters—no tuning hassles, just plug-and-play performance.

Ideal for throttle body injection (TBI) systems and late-model builds, these cams feature unique lobe profiles designed to work seamlessly with electronic controls. Whether you're upgrading a daily driver or a mild performance project, the Computer Controlled Series strikes the perfect balance between increased performance and system reliability.

For builders looking to maintain drivability while gaining noticeable power, a computer friendly TBI cam like this is the go-to solution.

Perfectly suited as a Comp Cam for TBI 350, this camshaft provides improved torque for better acceleration and towing capability without upsetting your vehicle's factory programming. That means less time reworking electronics and more time enjoying your build.

With a legacy of performance and innovation, Comp Cams delivers components that work right out of the box—no surprises, no compromises. The Computer Controlled Series is your ticket to easy, reliable power for fuel-injected applications.

Trust Comp Cams to help you build smarter, not harder. Bolt in confidence, drive with power.
