TRIFECTA Performance - Performance Tuning, Engine Calibration

The “Gen 1” 1.4L turbocharged engine (RPO:LUJ or LUV) can have some spectacular power gains from upgrading the OE turbocharger wastegate actuator, when combined with proper tuning!  This article goes into how boost control works on these engines (and turbocharged engines in general) and discusses the observed power gains from upgrading the OE wastegate actuator with a high quality aftermarket actuator.

Certain models of the 2011-2017 Buick Regal vehicles are equipped with additional mode buttons – one is labeled “GS” and the other is labeled “Sport”.  Depending on the features of the vehicle, these buttons may change the way the suspension operates, the way the accelerator pedal responds, and/or the way the automatic transmission shifts.

We've been fans of the Buick Regal ever since the days of the Grand National.  We were thrilled when, later, it was reintroduced in 2011 as a performance-oriented family sedan - it was on this platform that we established ourselves as the premier tuner for the Regal!  It is an honor to continue that legacy by yet again extracting more power and performance out of the NEW 6th Generation Regal!

Thus, we proudly present our calibration for the 2018--Present Buick Regal Sportback, Avenir, and TourX, equipped with the 2.0L Turbo (LTG) engine!

At TRIFECTA we believe it is our responsibility to serve the community first, and that the rewards for doing so will follow.  This article is about a recent encounter we had with a member of the community, how we served him, and how, by doing so, also helped contribute to our tenet of “Continuous Improvement”.

The horsepower wars are on with the GM 2.0L turbocharged LTG engine!  At the time of writing (early 2019), there's finally some exciting big power adders for the LTG engine on the horizon, and it's one of the best times to be modding the LTG engine!  TRIFECTA is pleased to show their contribution in this space, based on the Borg Warner EFR7670 turbocharger!
