Forza Motor Works Performance Bundle C8 Corvette ZR1

Unlock the performance potential of the twin-turbo LT7 with the Forza Motor Works C8 ZR1 Stage 1 Performance Bundle. The factory C8 Corvette ZR1 is already an exceptionally capable platform, but the restrictive factory catalytic converters and factory calibration leave significant performance on the table. This package combines freer-flowing intake and exhaust hardware with the HP Tuners components required to unlock the factory ECM for custom calibration. Package Includes SOUL Performance Competition Catless Downpipes Large-diameter 3.5" construction designed specifically for the C8 ZR1 Eliminates the restrictive factory catalytic converters Improves exhaust flow, turbo response, sound, and overall performance SOUL reports maximum gains of more than 100 WHP and 130 lb-ft of torque in portions of the powerband during independent testing Approximately 32.5 lbs lighter than the factory components Hand-built in the USA from T304L stainless steel Halltech Super Hornet Cold Air Intake High-flow intake system developed for the C8 ZR1 Massive dual-filter design with more than 600 square inches of filtration area Molded velocity stacks and reverse-flow funnels designed to maintain smooth airflow through both MAF sensors Increased airflow without requiring permanent vehicle modifications Designed to work with the factory turbo inlet ducting HP Tuners E68 ECM Upgrade Service Required to enable custom tuning of the factory Global B E68 ECM Original ECM is upgraded by HP Tuners Allows supported calibration, data logging, reading, and writing through the OBD-II port after the ECM is returned and installed ** YOU MUST REMOVE AND SHIP YOUR ECM TO HPTUNERS - LEAD TIME IS CURRENTLY 5-10 BUSINESS DAYS ** 10 HP Tuners Universal Credits Required to license the C8 ZR1 E68 ECM through HP Tuners Allows the upgraded ECM to be licensed for custom calibration Why This Package? The LT7 responds extremely well to increased airflow and reduced exhaust backpressure. The SOUL Competition Downpipes remove one of the largest restrictions in the factory exhaust system, while the Halltech Super Hornet increases available intake airflow to the twin turbochargers. Pairing these modifications with full HP Tuners ECM access gives your calibrator the ability to optimize boost control, fueling, ignition timing, torque management, and other critical engine parameters for your specific vehicle and fuel. Rather than combining individual components that may or may not work together properly, the Forza Stage 1 Package provides the core hardware and tuning access needed to build a properly calibrated high-performance C8 ZR1. Fitment 2025+ Chevrolet Corvette C8 ZR1 5.5L Twin-Turbo LT7 Important Notes Custom ECU calibration is not included unless specifically selected or stated at the time of purchase. The factory ECM must be removed and sent to HP Tuners for their E68 Global B upgrade service before it can be custom calibrated through HP Tuners VCM Suite. Additional tuning hardware or software may be required depending on who is performing the calibration. SOUL Competition Downpipes eliminate the factory catalytic converters and are intended for competition/off-road applications where legally permitted.
