General Motors has begun encrypting the control modules of its products, starting with the Cadillac CT4, CT5 and C8 Corvette. This is then followed by the latest generation Chevrolet Tahoe and Suburban, Cadillac Escalade, and GMC Yukon family. It continues with the 2022 Chevrolet Silverado 1500 and 2022 GMC Sierra 1500 that were recently unveiled. As a result, the stock ECU and TCU are impossible to tune and calibrate, leaving people to go to great lengths to circumvent this obstacle via piggyback control units and a rats nest of wires. Oftentimes, the vehicles are broken. So it’s largely an internet novelty to give a supercharged C8 Corvette Stingray 1,000-plus horsepower, as these tradeoffs are largely unappealing to most customers. However, Lingenfelter Performance Engineering and Magnuson Superchargers may have come up with a solution.
Lingenfelter C8 Corvette Stingray: 705 Supercharged Horsepower
Not to rain on the 2023 Corvette Z06 and its 670 horsepower via the awesome new LT6 V8 engine, which debuted earlier this week, but the teaser video from Lingenfelter alleges 705 horsepower, and 667 lb-ft of torque. That a gain of over 200 horsepower, and nearly 200 lb-ft of torque. Simply amazing. To get it done, Lingenfelter looped in Magnuson Superchargers for its development. The partnership can also be found in the 2019+ Chevrolet Silverado 1500 and GMC Sierra supercharger kits that were announced and priced earlier this week.
Lingenfelter says that the package took over a year to develop, with hours and hours of testing on the dyno, making it the most comprehensive power upgrade for the C8 Corvette Stingray we’ve seen yet. We hope to learn more about this supercharged C8 Corvette Stingray from Lingenfelter at the 2021 SEMA Show in the coming days. Was the encrypted ECU cracked? We’re not sure, but expect the latest details to be published on MC&T before you see it anywhere else.
