Derringer Is the Best Inline Tuner For Your Duramax

You love your truck. It’s a dependable workhorse that never lets you down. But it could use more power. You’ve read about tuning your ECM on the internet and the idea of sending your engine’s computer off to someone else and leaving your truck inoperable for days isn’t that appealing, or is voiding your warranty because you’ve altered your truck’s brain. What you need is an in-line tuner and when it comes to in-line tuners, Banks’ Derringer tuner is engineered better than any other. 

What’s an in-line tuner? Simply put, the compact electronic module intercepts a handful of data signals from engine sensors and manipulates their signals in such a way that the engine computer makes more power and torque. People have been tuning vehicles this way for decades and it’s a safe, non-invasive way to get some more performance from your ride.

So why Derringer? That’s an easy one too. Nobody offers the combination of performance uplift across the operating range of your engine and safe, no-compromise tuning that Banks does. We came up with this tuning ethos over six decades of performance engine building and racing, and it works.

Another big benefit to Derringer is the sheer number of maps we include for each tuner. Some of the competition may only have one or two maps – a performance map and a fuel economy map, for example – while Derringer offers six that you can adjust on the fly through your iDash digital gauge. Want to take your neighbor out and scare him a little? That’d be Level 6 for max power and torque. Towing and want to take it a little easier? Try level 3 or 4. Trying to get every last MPG that your truck has to offer? That’d be level 2.

The Derringer is relatively easy to install, and should you choose to remove it, it leaves no fingerprints in the engine’s computer. This means your dealer should have nothing to complain about when it comes to warranty work.

Banks’ Derringer tuner is available in standard and High Output versions, depending on your application and requires a Banks iDash for installation.
