The Katech Installation Process
Vehicle Inspection
Before installation begins, the vehicle is evaluated for mechanical concerns or existing modifications that may affect package installation and calibration. This helps establish a foundation for the completed Stage 1 upgrade.
Baseline Dyno Testing
Baseline chassis dyno testing is performed to document the vehicle's incoming performance before modifications. These results provide a reference for evaluating the completed package.
Halltech Cold Air Intake Installation
The Halltech MF103 Black Killer Bee cold air intake is installed to improve induction airflow into the LS3 engine. The intake system is designed to reduce restriction compared with the factory intake configuration and complement the other Stage 1 upgrades.
Katech CNC-Ported Throttle Body Installation
The Katech LS7 CNC-ported throttle body is installed to improve airflow through the throttle body assembly. Its CNC-ported design complements the Halltech intake and helps support improved engine response.
Cooling System Service
A 160-degree thermostat is installed as part of the package. GM Dex-Cool coolant is included for the associated cooling system service. The thermostat changes the temperature at which coolant circulation begins but does not independently guarantee a specific operating temperature.
Wideband Tuning Preparation
The included wideband O2 bung, plug, and washer provide the necessary provisions for wideband oxygen sensor use during the tuning process.
HP Tuners Calibration
Using HP Tuners software and included credits, Katech calibrates the LS3 engine management system to account for the upgraded induction components and optimize the engine's operating characteristics.
Chassis Dyno Tuning
The vehicle receives chassis dyno tuning to evaluate engine performance and refine the calibration. Dyno testing allows Katech to assess the completed package and compare performance against the baseline results.
Street Drivability Calibration
Following dyno tuning, the vehicle receives street calibration to refine throttle response, part-throttle operation, and everyday drivability. The goal is to deliver responsive performance with predictable operation during normal driving.
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 460HP package combines carefully selected induction components with professional installation, chassis dyno tuning, and street calibration to deliver a balanced LS3 performance upgrade.
Every Katech Installed Performance Package is built around professional installation, calibration, validation, and support from the Katech team.
