3.0 liter Duramax Derringer Development

Testing and tuning has begun on the Banks Derringer for GM’s new 3.0 liter Duramax turbo diesel. Just introduced in the 2020 model year for the Chevrolet Silverado and GMC Sierra, this new offering is attracting customers who have wanted the power and torque of a diesel but don’t necessarily have the need for the Earth moving power of the 6.6 liter L5P. But, as with any diesel can attest to there’s always the hunger for more power. Luckily the Derringer and iDash combo is the answer for reliable power and torque improvements.

Our engineers have been hard at work testing and tuning to get the most power available. In addition to the power improvements we’re adding in the class-leading advanced safety features like AutoRate® adaptive tuning to deliver peak performance under every driving condition, TransCommand® active transmission safety to enhance shift performance and improve the longevity of your transmission, and ActiveSafety® that ensures smooth operation that will never leave you stranded. Lead Engineer Jeff Lee continues to fine-tune the various levels of calibration on the dyno and on the road for drivability and power delivery.
