800 HP Supercharged LT5 Performance with Halltech Cold Air Intake, Katech CNC-Ported Throttle Body, and Professional Dyno Calibration!
Professionally Installed and Dyno-Tested Performance for the GM LT5
The Katech C7 ZR1 Corvette Stage 1 800HP Installed Performance Package is a professionally engineered performance upgrade designed to deliver 800 horsepower from the factory-supercharged GM LT5 6.2L V8. Developed specifically for the 2019 Chevrolet Corvette ZR1, this package combines improved induction airflow, upgraded cooling system components, and custom ECU calibration to enhance the performance of Chevrolet's flagship C7 Corvette.
At the center of the Stage 1 package is the Halltech Stinger RZ cold air intake, paired with a Katech CNC-ported 95mm LT5 throttle body. These components are designed to improve airflow into the factory LT5 supercharger system, supporting increased horsepower and improved throttle response while retaining the original supercharger and internal engine components.
The package also includes a Katech billet thermostat housing, 160-degree thermostat, and supporting wideband oxygen sensor hardware for calibration. The factory E99 engine control module receives the required HP Tuners unlock, allowing Katech to perform custom ECU calibration tailored to the upgraded induction system.
Every Stage 1 package includes professional installation, baseline dyno testing, chassis dyno calibration, street drivability calibration, and a serialized Katech plaque. The result is a complete performance upgrade that enhances the capabilities of the C7 ZR1 while maintaining the factory LT5 engine architecture.

The Katech Installation Process
Vehicle Inspection
Each vehicle is inspected before installation begins to identify any mechanical concerns that should be addressed before modification. This initial evaluation helps establish a foundation for the completed Stage 1 performance package.
Baseline Dyno Testing
Baseline chassis dyno testing is performed before modifications to document incoming vehicle performance and establish a reference point for evaluating the completed package.
Cold Air Intake Installation
The Halltech Stinger RZ cold air intake is installed to improve airflow into the factory LT5 supercharger system. Designed for the C7 Corvette ZR1, this intake supports the increased airflow requirements of the Stage 1 performance combination.
Katech CNC-Ported Throttle Body Installation
The factory LT5 throttle body is upgraded with a Katech CNC-ported 95mm unit. The porting process is designed to optimize airflow through the throttle body while retaining its original 95mm architecture, complementing the Halltech cold air intake and factory supercharger.
Cooling System Upgrades
A Katech billet thermostat housing and 160-degree thermostat are installed as part of the package. These components modify the engine coolant thermostat configuration to support the completed performance combination.
HP Tuners E99 ECU Unlock
The factory LT5 E99 engine control module requires an HP Tuners unlock before custom calibration can be performed. The Stage 1 package includes this unlock service and the required HP Tuners credits, allowing Katech to calibrate the factory ECU for the upgraded induction system.
ECU Calibration
Following the ECU unlock, Katech develops a custom calibration appropriate for the Stage 1 800HP performance combination. Calibration is tailored to the Halltech intake, CNC-ported LT5 throttle body, and overall operation of the factory-supercharged LT5 engine.
Dyno Calibration and Validation
After installation, the vehicle receives chassis dyno calibration and performance validation. Dyno testing is used to evaluate the completed package, refine calibration, and compare performance against the original baseline results.
Street Drivability Calibration
Following dyno calibration, the vehicle receives street drivability calibration to refine throttle response, idle quality, part-throttle operation, and general driving characteristics. The objective is to deliver increased performance without sacrificing the everyday usability expected from the C7 Corvette ZR1.
The Katech Difference
Katech Engineering has been developing, machining, assembling, and validating high-performance engines and components since 1977. From professional motorsports programs to premium street performance packages, Katech focuses on complete engineered systems rather than random combinations of parts.
The Stage 1 800HP package takes advantage of Katech's engine development, precision CNC machining, professional installation, ECU calibration, and chassis dyno validation capabilities to deliver a complete performance upgrade for the LT5-powered Corvette ZR1.
Every Katech Installed Performance Package is built around professional installation, calibration, validation, and support from the Katech team.
