The COMP Cams XR276HR computer-controlled Xtreme Energy cam is intended for modified TPI setups and higher-performance street builds. It requires TPI modifications—upgraded injectors, plenum and runners—plus exhaust work and a higher-stall converter (2000+ rpm). Custom tuning is necessary to match fueling and timing to the cam's profile for reliable operation and peak performance.
