Revive the Legend of the "Rocket"

This isn't just your father's Oldsmobile. It's a piece of history. Make it fly again.

Oldsmobile defined American innovation for over a century. Whether you are piloting the technologically advanced Aurora, the bulletproof Intrigue, or the versatile Bravada, you are driving a legend. But time takes its toll. The factory tuning on these late-90s and early-2000s vehicles is often overly conservative, and age can make the throttle response feel sluggish and heavy.

The Stage 3 "Rocket-Spec" Performance Module is the restoration tool your engine needs. Engineered to optimize the legendary GM 3800 V6, the Northstar-derived V8, and the 3.4L V6, this OBDII module wipes away the years of delay, restoring the smooth, authoritative power that Oldsmobile was famous for.

Wake Up the Aurora V8. Modernize Throttle Response. Smoother 4-Speed Shifting.


Why Upgrade to Stage 3?

  • The "Rocket" Revival: Safely unlock up to +35 Horsepower and +40 ft·lbs of Torque. Whether you have the 4.0L Aurora V8 or the 3.8L V6, feel the surge of power that these engines were capable of when new.
  • Fix the "4-Speed Slush": The 4T65-E automatic transmissions were known for lazy shifts. We optimize the shift logic to hold gears longer on acceleration and downshift faster for passing.
  • Intrigue & Alero Agility: For the sportier models, the chip sharpens the throttle response, giving the car the "import fighter" feel it was designed to have.
  • Bravada Towing: For SmartTrak AWD owners, the added low-end torque helps the SUV get moving quickly, even in poor weather or when towing a trailer.
  • Universal Compatibility: Works seamlessly with all OBDII Oldsmobiles (1996-2004), including the Aurora, Intrigue, Alero, Bravada, Silhouette, 88, and Cutlass.
  • Plug & Play Restoration: Installs in under 60 seconds via your OBDII port. No tools, no mechanic, and no greasy hands.

Smart Tuning for GM's Best Engines

Oldsmobile used some of General Motors' finest powertrains. The Stage 3 Tuner optimizes them for modern traffic.

The 3800 V6 (Series II/III): Widely considered one of the best engines ever made. Our module advances the spark timing to wake up this sleeping giant, giving it a surprisingly aggressive mid-range pull.
The Aurora 4.0L V8: A high-tech masterpiece. The factory tune was soft to prioritize quietness. Our chip sharpens the fuel curves to let that DOHC V8 sing near the redline.

100% Safe for Older Engines

We know preservation is key. The Stage 3 Performance Chip is 100% safe for high-mileage vehicles.

Non-Intrusive: The device operates as a piggyback signal modifier. It does not permanently rewrite your vintage ECU. It respects the factory safety limits of the engine. If you want to return to stock for a car show, simply unplug it. It is the easiest performance restoration you can perform.

Frequently Asked Questions

Will this work on my 1997 Cutlass or 88?
Yes. Any Oldsmobile manufactured in 1996 or later has the OBDII port. The chip works perfectly with the 3.1L and 3.8L engines found in these sedans.

Does it work on the Aurora V8?
Absolutely. The Aurora is one of our favorite applications. The chip helps unlock the performance potential of the Northstar-based V8, making the car feel much more like the luxury sport sedan it was meant to be.

Will it improve my gas mileage?
Old V8s and V6s can be thirsty. By optimizing the air/fuel mixture and increasing torque, the engine runs more efficiently at cruising speeds, often resulting in a 1-3 MPG gain on the highway.

Is installation hard?
It is effortless. The OBDII port is located under the dashboard on the driver's side. Simply plug it in. It is compatible with the "Classic" styling of your interior.
