Omni LT4 Street Package (Stage 2)

The Omni LT4 Street Package is our most popular performance package for Gen V LT4-powered Corvettes, Camaros, and Cadillacs. Designed for enthusiasts looking to transform the driving experience without sacrificing reliability, this package combines the industry’s most proven bolt-on upgrades into one complete, professionally installed performance package.

By increasing airflow, spinning the supercharger more efficiently, and pairing everything with a custom in-house dyno calibration, the Street Package delivers the horsepower, torque, and throttle response that every LT4 owner is looking for. The result is a car that accelerates harder, pulls stronger throughout the RPM range, and sounds every bit as aggressive as it performs.

Unlike piecing together modifications one at a time, the Omni LT4 Street Package has been developed as a complete combination. Every component has been selected to work together, providing reliable, repeatable performance while creating the ideal platform for future upgrades.

Every vehicle receives a complete inspection before tuning, fresh maintenance items, and a baseline dyno pull to establish where your vehicle started. Once installation is complete, your vehicle is professionally calibrated on our in-house chassis dyno to optimize air/fuel ratio, ignition timing, throttle mapping, and overall drivability for your specific combination.

• Roto-Fab Cold Air Intake
• GripTec 2.30” Upper Supercharger Pulley
• Gates Supercharger Belt
• American Racing Headers

Expected Performance

Customers can typically expect gains of 50–70 rear-wheel horsepower, depending on the vehicle, transmission, fuel quality, and current condition of the vehicle. Results will vary between Corvette Z06, Camaro ZL1, and Cadillac CTS-V models, as well as automatic and manual transmissions.

While peak horsepower numbers are impressive, the biggest difference is how the vehicle feels on the road. Increased torque throughout the RPM range, quicker throttle response, and improved power delivery create a driving experience that’s noticeably stronger every time you get behind the wheel.

The Omni LT4 Street Package is perfect for:

• Owners looking for the best all-around bolt-on performance package.
• Daily driven vehicles wanting significantly more power without sacrificing reliability.
• Weekend street cars and occasional drag strip or roll racing events.
• Customers looking for a proven package before moving into camshaft or higher horsepower combinations.
