Trifecta Performance PCM Flash, 08-10 HHR SS

Model Number: 243192-KIT

Introducing one of the best tunes available for the 08-10 Cobalt SS Turbo.

The Trifecta tune will give you a solid 30 HP and nearly 70 ft-lbs of torque within minutes.

Plus, you can keep your factory tune and activate the Trifecta tune with either the cruise control button (cruise control is still functional), or the traction control button (hold down for 6 seconds to disengage traction control and activate the tune). This way you can have the gas sipping, 15 psi factory tune when other people drive your car, and activate the Trifecta tune to jump to 20-23 psi when you want more power!

The Trifecta tune is installed easily with your laptop computer and a PC update cable. We'll email you a tune that's custom made for your specific mods, and mail you an update cable. The ECU flash is priced at $299.99 and the update cable is an additional $200.00. Once you upload the tune to your ECU you may keep the cable for future updates, or you return it for a full refund of your deposit.

Pictured below is a dyno chart of our 2009 Cobalt SS Turbo, with an intake, downpipe and exhaust. This vehicle was making 263 wheel HP (stock is ~235-240 wheel HP) and 263 ft-lbs of torque on 15 psi of boost.

Once the Trifecta tune was activated, our boost jumped to 20-23 psi (depending on temperature, and gear), making 293 wheel HP and 329 ft-lbs of torque. The car is now a BEAST with the Trifecta tune engaged!

Note: There are two important things to keep in mind when ordering a Trifecta tune for your 08-10 HHR SS.

  • If you have a GM Stage 1 Kit installed, please make note of this in the additional modifications field, as the tune must be calibrated to account for this.
  • Do you have a "Brake Vacuum Pump Kit installed on your HHR SS? If you are not sure, see the photos below to make sure you select the correct option in the field above.

Please allow 5-7 business days for Trifecta to custom write you a tune. The cable will ship separately from us, once your tune is available we will email you the tune directly. The shipping you select in the cart is how fast you will get the cable not the tune.

    i have a 08 hhr ss that is bone stock. would the trifecta performance tune still work fine with my car or is this meant only for cars that have upgrades to them, such as different air cleaner, downpipe, exhaust, etc.

    or would you recommend i do some upgrades first before the tune

      We recommend adding a few bolt ons to your vehicle to take advatage of the full tune before installing it to your vehicle.
  • Zach
    I have hhr ss and was looking at doing the tune. I have mild bolt ons and such but I want the tune to come on when car is put in competition mode so it contains the stock launch control an I or my wife can drive car in stock mode when not in competition mode. Is this possible or is it a complete different set up? Thanks

      Yes, no problem, you have the option for cruise control button activation, or traction control activation, you wont the traction control button activation.

    I am wondering if this tune would be compatible with a catless downpipe with o2 bung. Will it keep the check engine light from coming on?

      Yes, this tune does not monitor the downstream o2 sensor, which prevents the check engine light from coming on.

    Hello, I have the stage 1 tune from GM and it's pretty healthy , is this even better ,and can I keep the GM tune to switch back and forth with the Trifecta ? Just wondering if it's worth getting with the GM Stage 1 thanks . Corey

      There is a small gain with this flash over the GM stage 1, but not a substantial amount. We'd recommend you just stick with the GM stage 1 unless you are trying to squeeze every last horsepower out of the car.
