Here Are The GM Vehicle Tuning Projects Trifecta Is Working On6
In case you missed it, Trifecta Performance is digging into the GM catalogue to tune for more performance, on demand. Now, we’re taking a closer look at the list Trifecta Performance tuning projects, past, present, and future.
Looking over the list, it appears as though Trifecta Performance is keen to offer upgrades for a broad variety of GM vehicles, including those beyond the usual performance suspects. For example, the tuner has already completed projects for the 2022 Chevy Malibu (turbocharged 1.5L I4 LFV gasoline engine), while working on new upgrades for models like the 2022 GMC Acadia (turbocharged 2.0L I4 LSY gasoline engine).
Additionally, Trifecta Performance has completed a tuning project for the turbocharged 2.0L I4 LTG gasoline engine under the hood of the Chevy Camaro, while working on projects for performance models like the Cadillac CT4-V Blackwing (twin-turbo 3.6L V6 LF4 gasoline engine), Cadillac CT5-V Blackwing (supercharged 6.2L V8 LT4), and Chevy Corvette C8 (naturally aspirated 6.2L V8 LT2).
These last three vehicles are especially important, as all three run the latest GM Global B electrical architecture. Also known as the Vehicle Intelligence Platform, Global B offers myriad benefits for factory stock vehicles, including greater processing power, over-the-air updates, the latest digital features, and, critically, improved security. However, it’s this latter bit that’s proven to be particularly troublesome for tuners, as the high-level encryption that’s baked into the Global B platform makes tuning difficult, if not impossible.
Nevertheless, Trifecta Performance has developed a solution to these issues, becoming the first company to natively tune the C8 Corvette ECU. Rather than engage a piggyback ECU workaround like other tuning companies, Trifecta has developed a method to tune system parameters directly, including the air-to-fuel ratio, ignition timing, fuel injection, cam phasing, and the like, all of which is critical when adding power adders and other performance upgrades.

On a seperate note, whats the deal with lingenfelter and making a supercharger kit for the blazer? Are they not doing it?
I have serious concerns about the AWD transfer case being able to handle it. We looked into this for AWD variants of the Chrysler 200S, with its rear-bias AWD and 300 hp V6… on paper it was the perfect car to get a supercharger.
But with PTU’s already failing on them at 300 hp, pushing it to 400+ is really, really risky.
I suspect the PTU on the Blazer will have similar issues handling that much power.
The torque output is not the PTU root problem unless they are defective. We put almost 400 lb-ft of torque on a 2013 Cadillac ATS4 and never had a problem.
Well first the ATS has a stronger AWD than any FWD car this side of Lancer. But I’m not talking about torque, I’m talking about adding 100 hp to an AWD system which wasn’t designed to handle more than 300 hp in the first place.
Cherokee has the same AWD setup as 200S, but 50 less hp. It’s holding up fine, but the 200S V6’s are failing.
It wouldn’t surprise me if that’s holding the Blazer supercharger back. If it’s not that it’s the suspension. Certainly no HiPer struts on that car.
My 400 lb-ft of wad flowing almost 30 lb/min of air for about 320 hp. That was on pump gas and not E85 or with a bigger turbocharger. Also had a Buick Envision 2.0T with HiPer strut that had over 360 lb-ft of torque without problems.
And before that I had a XTS Vsport 3.6TT that putting out over 550 lb-ft of torque and would spin thr front tires at 50 mph in 90°F heat. It is torque that kills transmission and components not hp.
No tuning on the LM2, hopefully they can get a little more out of the little diesel
