Welcome to TerrainForum!

As the premier tuner for both Theta and D2XX platform Cadillac SRX, Chevrolet Equinox, and GMC Terrain, we at TRIFECTA Performance have always done our best to keep the platform fresh and exciting - whether it be by developing useful and innovative features, or by supporting the latest aftermarket hardware.

For anyone unfamiliar with how our tuning works, we develop and maintain our own software and interface hardware for tuning the various GM models we support.

17841


17842


17843


Developing our own tuning solution gives us the flexibility to locate and tune any parameter we need to, or in some cases, add our own custom code to the vehicles powertrain control modules!

We leverage this ability to deliver features like Driver Selectable Vehicle Modes, Performance AutoStop Mode, and others.

17839


Beyond the software, we also perform in-house development of our products via a combination of long-term street and dyno tuning. This method ensures the quality and reliability of our products, and allows us to offer competitive pricing.

Wheel Tire Vehicle Car Automotive tire


To that end, we have two simple service levels/price tiers:

TRIFECTA Advantage:

17838


If your vehicle is stock, or has certain modifications which "just work" and do not require tuning, you can simply plug and play with our "canned" tune. Advantage customers receive full customer support for as long as they own their vehicle. Further customization is not offered at this tier, and the price reflects it. It is a great entry level option if you don't plan to modify the vehicle beyond just the tune.

TRIFECTA Elite:

17840


If you have any mods which require tune customization, or have special requests, our Elite tier offers unlimited updates for mods/requests for as long as you own the vehicle.

There are no extra charges once you go Elite, and if you have Advantage already, you can simply upgrade to Elite for the difference in price at any time.

Regardless of which tier you choose, rest assured you’re getting a committed and dedicated support and service team to answer your questions, provide recommendation on mods, and provide any assistance you may need before, during, and after your purchase with TRIFECTA.

We are only a click away via the links in our signature!

Hey durdy1, thank you for your interest in TRIFECTA products! This is a vehicle we plan to offer product for, but at this time we do not have one, or an ETA. Feel free to check in with us periodically via our website for any updates!

Hi @04 commemorative ,

Our product for the Terrain 2.0T essentially harkens back to the way I remember a tuned Cobalt SS feeling going from stock to tuned. Plenty of torque available down low, the feeling of the vehicle wanting to keep pulling for as long as you want it to, and just silly enough to make you smile every time you punch it. :)

For more technical info, you can check out our product page:


For a general sense of what to expect from us and our products, this is what our customers have to say:

Useful and innovative features like what?

Add your own custom code how?

I see and hear about all this "tuning" going on, but I don't understand exactly what you guys are doing. Are you:

1.) Replacing the original computer program from the manufacturer ... OR ..
2.) Adding code/logic to the original computer program from the manufacturer... OR
3.) Just tweaking parameter values and "flags" to "turn ON" some basic features that a particular model's trim level didn't come with from the factory?

Hi @Colt Hero ,

It depends on application, but we've developed features which add functionality outside of the scope of what the manufacturer provided from the factory. Features like disabling autostop, switching between an "ECO" and a "Sport Mode" on the fly via the cruise control button, special provisions for aftermarket modifications like forced induction, flex fuel, etc.

As for what "tuning" is in the context of our product, its a mix of 1,2, and 3, whereas with other software it is primarily only 3.

Beyond adding our own code to facilitate our custom features and pushing/pulling levers in the ECM, we also extract more performance out of the vehicles we tune via street and dyno testing, and spend a lot of time on the more subjective task of morphing driving character into something more exciting to drive while (mostly) keeping fuel economy in tact. Its a labor of love for sure, especially when it comes to platforms most people don't associate with tuning like the Nox/Terrain. We've owned 3 (?) Equinoxes and 3 Terrains over the last 10 years or so, and plan to continue the trend as long as GM keeps making them!

I did a Trifecta tune in my' 15 2.5 Malibu as it was not much more costly than a plug in Auto stop killer and I definitely got my money's worth.
Original goal was to kill the AS but now no AS and improved throttle and trans logic that made a family sedan feel more sporty. Less short shifting and trans. just trying to get into OD as soon as possible with constant back shifting in/out of OD.
WFO it will ping on regular when wound up but keep the gas pedal off the floor and runs on regular just fine.
Reversible and a invisibility options also.
My personal experience with the Trifecta tune in a GM 4 cylinder.
Your mileage may vary.....

How does your "Start/Stop" disable work? Is it the "Hood Trick" the other guys do?

switching between an "ECO" and a "Sport Mode" on the fly via the cruise control button
How does that work? You can't "normally" switch these "on the fly" with the factory-supplied program?

How are you changing the factory program in the ECU? Are you replacing the ROM wholesale, or downloading a new program to it?

Hey @Colt Hero ,
  • We reprogram the ECM to disable AutoStop. No "tricks" necessary! On vehicles equipped with an AutoStop button, we can tell it to start off disabled, but still allow the driver to re-enable it via the button. On some platforms, we offer "Performance AutoStop Mode" (PASM), where AutoStop is only disabled when using the performance-oriented side of our tune (CC disarmed). For these platforms where we offer PASM, we still offer the option to just disable the system outright if the customer requests it.

  • For our switchable tunes, we add custom code to the ECM (via programming) to "listen" to the arming state of the cruise control system via the CAN bus, and switch to a different map depending on the state.

  • Programming ECMs in general involves replacing the programming either entirely, or incrementally. When you flash our calibration to a stock vehicle, it replaces the entire image with ours. If you receive a tune update from us, then it only flashes the bits that changed (incremental). Flashing back to stock again replaces the whole image and restores the ECM back to its factory fresh state.

Is this ECM program replacement sanctioned by GM (or any other auto manufacturer), or are you doing this "on your own"?

@Colt Hero That would require TRIFECTA to convince GM and the EPA that durability and emissions compliance aren't negatively affected, which, of course, they can't do. That is why they emphasize how easy it is to return to stock tune for warranty or emissions testing.

I'll add invisibility mode in my older tune makes it dealer friendly not to mention as Alan said 5 min. to re flash stock tune back into the car.

What about Warranties? I assume owners are only doing these "tunes" after their Warranties have expired?

Honestly - I don't know why Manufacturers aren't doing everything possible to block these "tunes" from being installed because ... it could end up causing them a lot of trouble ... from wasted time debugging non-problems, to (worst case) fatalities that some lawyer decides to prosecute forensically!

I think as EVs become more mainstream, and automobiles become more software-driven, you're going to see more effort put into making these programs "tamper-proof".

It's human nature to want to break things that aren't broken. People install aftermarket blower kits and when the motor blows up they remove all evidence of the kit and have it towed to the dealer. "Gee, I don't know what happened, it just stopped running."

I've seen cylinder heads returned from the field with the valves tuliped so badly you could use them for shot glasses. Impossible to without LOTS of boost on an engine not designed for it, yet the dealer claimed no evidence of aftermarket tampering. BS.

Funny you should mention it, we recently completed CARB testing for ALL of our 4 cylinder turbocharged engine applications. The process for obtaining the actual certification has been long and drawn-out, but we passed!

Regarding warranty, we make no guarantees what a dealer will choose to do with it. Anyone considering modifying their vehicle in any way should be prepared to lose it. We've actually written an article on this topic:

1.5 in Malibu's the PCM is locked by GM currently. Not the 2.0 . I believe tuning a 1.5 in them is a send out the PCM to a tuner for programming as it can't be done via OBD port. 1.5 is close to the edge in stock form and there have been piston issues in the past with the 1.5 Malibu's so GM locked them down to prevent ''quickie'' tunes.
A few other Mfgrs. are locking PCM's but over time they can and will be cracked.
30 + mpg and 300 hp is not realistic and a long term reliable reality.
