As GM Authority covered previously, GM has been hardening its Global B-based vehicle components with enhanced cybersecurity. However, these efforts also make these components more difficult to modify, thus making it harder for tuners to extract additional performance from Global B-based GM models. Nevertheless, where there’s a will, there’s a way, and Lingenfelter is already offering a new supercharger kit that’s compatible with the 2025 Silverado and 2025 Sierra pickup trucks.
Per the Lingenfelter website, the supercharger kit is available for 2019-and-newer Chevy Silverado 1500 and GMC Sierra 1500 pickups equipped with either the naturally aspirated 5.3L V8 L84 gasoline engine or the naturally aspirated 6.2L V8 L87 gasoline engine. The package includes Magnuson’s TVS 2650 GM DI Truck Intercooled Supercharger, as well as Lingenfelter Performance Engineering’s integrated control system, yielding over 150 additional rear-wheel horsepower and over 100 additional rear-wheel torque. Not bad for a pickup like the 2025 Silverado.
With 6 psi of boost, Lingenfelter estimates peak output figures of 545 horsepower with 535 pound-feet of torque from the 5.3L V8 L84, and 650 horsepower with 630 pound-feet of torque from the 6.2L V8 L87. Lingenfelter notes that the system requires that the ECM is unlocked, and as such, customers are asked to mail their ECM to Lingenfelter, with an estimated two-week turnaround once the ECM is received.
Naturally, pricing for all this isn’t cheap. The package itself is $6,250, while installation and calibration for Global A vehicles is currently $11,995. Installation and calibration for Global B vehicles, such as the 2025 Silverado and 2025 Sierra, is currently listed at $13,495 (both installation and calibration prices are currently on sale).
As GM Authority covered earlier this month, General Motors is actively “hardening” various Global B components with enhanced cybersecurity measures, making them more difficult for tuners to crack. According to sources familiar with the matter, GM’s engineers analyze the ways in which a tuner may have “broken into” a controller, then create a patch to prevent it from happening in the future.
However, what actually happens is a a sort of “whack-a-mole” where tuners and GM engineers go back and forth in either cracking or patching these components.
Apparently, Lingenfelter plans to offer a supercharger kit compatible with Global B-enabled GM SUVs next.

Really not a bad price for the upgrade. GM charges 40 grand for the same upgrade when you go from a base C8 to a ZO6.
This should be a factory installed option. Charge $10k from dealership, with retuning and 3 year warranty. They have all the stuff they need from years of ZR1, ZL1, and Blackwing V Cadillacs. It’s ridiculous that in the end of 2024 GM has no answer for the Raptor R or TRX/RHO trucks. It truly upsets me.
I would wait until the bearing issues are resolved, which may be by the end of the generation.
MY24s have suffered failures, so I need to know if any MY25s have failed YET….
Why would GM want to lock out tuners? The aftermarket/3rd party ecosystem is a strategic asset for any product platform that creates demand and stickiness for the brand (see many examples in software industry like the Apple apps).
It would seem to me that the better strategy would be to do the cyber improvements and create APIs with a formal licensing and authorization program for legit tuners where they can unlock the code and build their enhancements and even have them available on a GM “App Store” that demonstrates these products meet GM’s requirements!
