The Katech Installation Process
Vehicle Inspection
Each vehicle is inspected before installation begins to identify any concerns that should be addressed before modification.
Baseline Dyno Testing
Baseline chassis dyno testing is performed before modifications to document incoming vehicle performance and establish a reference point for the completed package.
Professional Installation
All included components are installed by Katech technicians using established installation and assembly procedures. The Halltech STR Stinger intake, Halltech coupler, Katech CNC-ported throttle body, 160-degree thermostat, billet thermostat housing, and required supporting components are installed as part of the complete Stage 1 package.
ECU Calibration
The package includes the required HP Tuners credits and custom ECU calibration appropriate for the Stage 1 480HP performance combination. Calibration is optimized to support the upgraded induction components and overall engine operation.
Dyno Calibration and Validation
Following installation, the vehicle receives chassis dyno calibration and performance validation to verify the operation of the completed package and evaluate performance gains compared to the baseline results.
Street Drivability Calibration
After dyno calibration, the vehicle is road tested and calibrated to verify throttle response, part-throttle operation, idle quality, and overall street drivability before delivery.

Frequently Asked Questions
▾ Does this package include installation?
Yes! All listed parts are professionally installed by Katech Engineering as part of the Stage 1 package.
▾ How much horsepower does the Stage 1 package make?
The Stage 1 package is rated at 480 engine horsepower in the specified configuration. Actual output may vary based on vehicle condition, fuel quality, environmental conditions, and other factors.
▾ What vehicles are compatible with this package?
This package is designed for 2014-2019 Chevrolet Corvette C7 Stingray and 2017-2019 C7 Grand Sport models equipped with the naturally aspirated GM LT1 6.2L V8 engine.
▾ Is this package naturally aspirated?
Yes. The Stage 1 package produces its increased performance without adding a supercharger or turbocharger.
▾ Does this package require internal engine modifications?
No. The Stage 1 package focuses on bolt-on induction upgrades, cooling system components, and ECU calibration without requiring camshaft, cylinder head, or other internal engine modifications.
▾ What are the benefits of the Katech CNC-ported throttle body?
The Katech CNC-ported LT1 throttle body is designed to improve airflow through the factory throttle body assembly. When combined with the Halltech STR Stinger intake and custom ECU calibration, it supports improved engine breathing and throttle response.
▾ Why does this package include a 160-degree thermostat?
The Katech 160-degree thermostat begins opening at a lower coolant temperature than the factory thermostat, providing an additional cooling system modification for the performance combination. Actual operating temperatures depend on ECU calibration, cooling system operation, and driving conditions.
▾ Will my C7 Corvette sound different after installation?
The Halltech STR Stinger intake may provide a more noticeable induction sound compared to the factory intake system. This package does not include exhaust system modifications, so exhaust volume and character will primarily depend on the vehicle's existing exhaust configuration. Contact Katech sales for additional exhaust options.
▾ Is the advertised horsepower figure measured at the rear wheels?
No. The advertised 480 horsepower figure represents engine horsepower rather than rear-wheel horsepower.
▾ Is tuning included?
Yes. The package includes required HP Tuners credits, custom ECU calibration, chassis dyno calibration, and street drivability calibration.
▾ Is baseline dyno testing included?
Yes. Baseline chassis dyno testing is included to document the vehicle's performance before installation and provide a reference for evaluating the completed package.
▾ Does this package include a warranty?
Yes. The Stage 1 package includes a 1-year / 12,000-mile Katech limited warranty. See Katech limited warranty terms and conditions for complete coverage details, limitations, and exclusions.
