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.


Choose Your Power Level

The Stage 3 "SS-Spec" is our most popular option, designed to deliver the maximum safe power for both work and play.

Performance Module HP Gain (Max) Torque Gain (Max) Primary Benefit
Stage 1 +25 HP +20 ft·lbs Fuel Economy (MPG) Focus
Stage 2 +40 HP +35 ft·lbs Towing & Hauling Power
Stage 3 (SS-Spec) +60 HP +65 ft·lbs Maximum Street & Strip Performance

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.

Stage 3 performance chip

Overall I'll give a 3 out of 5. Hp gain I don't see any difference, acceleration,there's a little improvement, there is longer shifts,up to 6000 rpms,that's the most improvement I've noticed. This was the results of the 1st week, going to try 91 octane to see if I get better results.

Performance

I will update this comment in 2 or so weeks:

I received my chip yesterday and thought I would see immediate change of some kind. I didn’t really expect power as it says you gotta drive for some time but I at least expected the top speed to be changed and nothing. The top speed of my Camaro is still 147 MPH. My 0-60 time is 5.4 secs right now. So far, no changes at all. I will update this post in 2 weeks to see if anything has changed and how much.

R
Robbie McLemore
Worth the money out of my wallet!

I bought and thought possibly I would see instantaneous results but that wasn't the case at all. After nearly a month I now can tell the total difference between before and then to now. All I can say is wow! Happy I went with this.

Good buy

Took about a week to feel low end torque, fuel has improved some and the power has opened up very noticeably by the third week. Worth the money. And no more governor on speedometer.

Easy install and that's about all

Doesn't pack as.much punch as it claims, and only raised my top speed by 3 miles an hour, I feel kinda jipped

Only worked for a short time

When I first install this it seem to make a big difference. However, after only a month my truck started having shifting issue. When I unhook it, it would start shifting fine. I tried calling and send 5 emails with no response. This is a lot of money for this and item. Now I have a piece of plastic that is no good. Big waste of money and poor support. Hopefully who reads will not have the same issues as me.

Great product!!

Was a little bit sceptical about purchasing the stage three chip but as soon as I put it in I could feel an immediate difference! No more sluggish take offs and a much smoother ride! I work on cars for a living and I will be recommending this product to my customers. Thank you so much!!

Noticeable Power Increase

After a few weeks I’ve noticed a definite increase in power. It’s quicker off the line and the shift points have changed a bit. Overall for the price of this module I see value for performance.

Stage 3 OBDII

So far I’m impressed. Throttle response is much better and seems to have more power at higher rpms. The only mods I have made are the chip and a cold air. Would like to open the exhaust with high flow cats and let it breath. I’m sure the chip will really come to life then.

My sonic has a 1.8 ecotec; added the chip...the car shifts quickly and smoothly. Cannot wait to add some upgrades to the mix.

Money well spent.

Product works. I have noticed improved acceleraton and passing ability. Not sure on gas usage yet, but overall satisfied.

Danny Moran
Stage 3 Performance Chip OBDII Module for Chevrolet

Felt the difference immediately! Everything works better. Motor does not bog down after each shift. I can see a difference in gas mileage, but have not done a calculation at this time. It is significant. HP...does not live up to the "up to 40", however it is improved. Overall very happy and module was a good purchase.



Thanks,

Danny Moran
