EnginePower: Banks Derringer L5P Engine Tuner

Real Power!

Like many other drivers you want more power not less, and you want to be able to prove it. Consequently, the Banks Derringer L5P tuner is the only tuning system that uses scientific metrics to get the job done. The folks at Banks tested every other tuner on the same dyno, the same day, using the same climatic conditions. To make things even more rigid the test session even employed the same technician just to make the point. After all that the Banks system was proven to be the only tuner that actually utilizes your truck’s ECU to create intelligent, provable calculations!

Here’s what we’re talking about:

Deep Torque Bending

More Horsepower At The Rear Wheels

NOTE: Dr. Performance and Stealth share the same circuitry. Test vehicle: 2017-18 Chevrolet Silverado 3500 Dually 6.6L Duramax L5P. Factory intake and exhaust. All tests run on the same truck, same day, same conditions. Tested on a Mustang Dynamometer, 10-second sweep.
