Unleash the True Heartbeat of America

Your Chevy was built to work hard and run fast. Don't let factory software hold it back.

From the job site in a Silverado to the track in a Corvette, Chevrolet engines are legendary for their durability and power. However, to meet strict government fuel mandates, GM detunes these engines from the factory. They introduce "throttle lag" and aggressive Active Fuel Management (AFM) that kills your momentum.

The Stage 3 "SS-Spec" Performance Module is the solution. Engineered specifically for GM’s LS, LT, Ecotec, and Vortec families, this OBDII module unlocks the raw power hidden inside your ECU. It transforms a sluggish work truck into a towing beast and a daily driver into a street machine.

✔ Maximum Towing Torque. ✔ Eliminate Dead Pedal. ✔ LS/LT Engine Optimized.

Why Upgrade to Stage 3?

• Legendary Power Gains: Safely unlock up to +60 Horsepower and +65 ft·lbs of Torque (on V8 models). Feel the difference immediately when merging or hauling.
• Fix the "Chevy Shake": Improves the transition smoothness of Active Fuel Management (AFM/DFM), reducing the shudder often felt when the engine switches between V4 and V8 modes.
• Instant Throttle Response: Modern Chevys suffer from "drive-by-wire" delay. This chip sharpens the signal, giving you instant acceleration the moment your foot hits the floor.
• Silverado/Tahoe Towing: Specifically tuned to hold gears longer under load, preventing the transmission from "hunting" when you are pulling a trailer or boat.
• Universal Bowtie Compatibility: Works seamlessly with Gas (Vortec/Ecotec/LS/LT) and Duramax Diesel engines across the entire lineup (Cruze, Malibu, Equinox, Camaro, Corvette, Trucks).
• 5-Minute Install: Plugs directly into your OBDII port. No tools, no grease, and no mechanic required.

Smart Tuning for GM Architectures

General Motors uses sophisticated "Global A" and "Global B" electrical systems. The Stage 3 SS-Spec Tuner is designed to navigate these systems safely.

The Science of Horsepower: Unlike cheap resistors that just dump fuel, this module uses a multi-core processor to analyze CAN-Bus data 500 times per second. It optimizes spark advance and air/fuel ratios in real-time.

For the V8s (5.3L / 6.2L): It prioritizes low-end torque, making the truck feel lighter and more responsive off the line.

For the Turbos (1.4L / 1.5L / 2.0L): It helps build boost faster, reducing the lag often felt in the Cruze, Malibu, and Equinox.

100% Safe & Warranty Friendly

We know you rely on your Chevy every day. The Stage 3 Performance Chip is 100% reversible. It does not permanently "flash" or rewrite your ECU.

Will this void my warranty? No.
Because the device functions as a piggyback system, it leaves no digital footprint. If you need to visit the dealership for service or recalls, simply unplug the unit. Your truck or car returns to stock factory settings instantly.

Frequently Asked Questions

Will this disable AFM/DFM (Active Fuel Management)?
While it does not permanently "delete" the V4 mode (which requires a $500+ programmer), the Stage 3 chip alters the load demand sensors. This often keeps the engine in V8 mode longer, reducing the annoyance of the system cycling on and off.

Does this work on the Duramax Diesel?
Yes! On the 6.6L and 3.0L Duramax, the chip optimizes fuel rail pressure and boost timing, providing significant torque gains for towing heavy loads without raising EGTs to unsafe levels.

I have a lifted Silverado with big tires. Will this help?
Absolutely. Big tires kill your acceleration. The added torque from the Stage 3 chip helps compensate for the heavier rotational mass, restoring the "pep" your truck had when it was stock.

Is installation hard?
It’s incredibly easy. The OBDII port is located under the dashboard on the driver's side. Plug it in, start the truck, and you are ready to go.
