Maximize your turbocharger spool velocity and power delivery across the mid-to-high RPM bands by upgrading to this elite, engineered Stage 1 performance profile. Purpose-built for modified setups utilizing bolt-on intake paths, high-flow exhaust piping, and software remapping, these camshafts completely eliminate cylinder head restrictions under intensive boost loads. They serve as the perfect valvetrain upgrade for street cars, track vehicles, or roll racing platforms looking to optimize volumetric efficiency safely. 
Maintain complete factory drivability and throttle response while flawlessly targeting robust engine power levels ranging anywhere from 550 to over 750 horsepower. Because this premium architecture works in flawless harmony with your engine's advanced Valvetronic lift system and Double VANOS variable timing hardware, you get massive top-end gains without sacrificing low-speed engine manners. This profile operates seamlessly alongside modern 58mm to 68mm performance turbochargers to ensure broad, unrelenting torque curves across the powerband. 
Prevent destructive high-RPM valve float completely under extreme manifold pressures by deploying these aggressive camshafts with required valvetrain upgrades. Because these advanced profiles deploy distinct opening slopes and specialized duration parameters, installing heavy-duty performance valve springs is a mandatory system requirement to safeguard your cylinder head hardware. Pairing this set with premium performance beehive valve springs ensures your mechanical assembly remains perfectly synchronized when tuning aggressively with pump gas or high-octane E85 ethanol racing blends.
