What to expect
- Quicker throttle response. Less of that dead spot when you roll into the pedal from a stop or to pass.
- More midrange pull. Merging, passing, climbing a grade with a load.
- Doesn't change your drive modes. Your factory drive modes stay as Chevrolet set them up.
- Realistic gains. It's a plug-in module, not a full ECU re-flash. Up to +40 HP / +45 lb-ft on turbocharged engines; non-turbo engines gain less.
How it works
The module plugs into your OBD2 port and works alongside the factory engine computer. It's adaptive: it reads how you're driving, from throttle position to fuel demand, and adjusts its output to match. Easy cruising stays smooth; get on it or tow and it gives you more. Nothing inside the engine computer is rewritten. Each chip is programmed in house for the make, model and year you enter and the options you pick.
Install in about a minute
- Find the OBD2 port under the dash on the driver's side.
- Engine off, connect the module with the included plug-in cable (long enough for any vehicle).
- Turn the key. The PWR, LNK and DAT LEDs confirm it's connected. Drive normally for a few trips.

Common Questions
Will it fit my Chevrolet?
If it has an OBD2 port (1996 and newer), yes: Silverado, Tahoe, Suburban, Colorado, Camaro, Corvette, Malibu, Equinox, Cruze and more. Pick your Engine Size and enter your make, model and year when you order.
How much power will I actually get?
Up to +40 HP and +45 lb-ft on turbocharged engines. Naturally aspirated engines gain less. You'll feel it most as sharper throttle and stronger midrange.
What does "adaptive" mean?
It watches throttle position and fuel demand and adjusts. Light cruising stays smooth; hard acceleration and towing get the full Stage 3 output.
Does it work on diesels?
Yes. Under Engine Size, pick 8 Cylinder for the 6.6L Duramax, 6 Cylinder for the 3.0L Duramax, or 4 Cylinder for the 2.8L Duramax.
Will the dealer know?
Unplug it before service and your Chevrolet is completely stock. Nothing stays behind in the engine computer.
Why does the module say JDM PROM?
JDM PROM is the brand name on the module and its retail box. Every unit is programmed in house for your specific Chevrolet make and model, assembled in the USA, and backed by our lifetime warranty and 30-day return window.
