Although our engineers are keeping the power numbers close to the vest, I suspect we'll see more power than we did in the previous generation of L5P. As GM improves the engine's thermodynamics, it giv

Jay from Banks here. Here's a little backstory on what it will take to get the Derringer, Ram-Air Intake, and Monster-Exhaust to market. The moral of the story is to be wary of any manufacturer that r

Yes, we sure are. We have Test Pilots evaluating the tuner right now. We hope to make an announcement in the next few weeks about its launch.

Hmmm, I thought the change in turbo (10- blade vs. 11-blade) and some of the other things Gale mentioned would have made the gen2 L5P have a higher ceiling...

The turbo upgrades raised the power level, not the ceiling. The ceiling is set by thermal and emissions limits.

What are the ceiling parameters? 

Are those Banks or GMs?

GM's ceiling. In other words, there are thermal limits like EGT, IAT, Mass Air Flow, etc, that GM doesn't allow you to exceed. The ECM fights back. Our job is to identify those limits through a few weeks of dyno tests, then back down Derringer's added power until everything is happy and repeatable.

Still waiting, truck pulling season is coming soon! Are we getting any closer?


@Knottyboyz Steve with Banks here. Yes, we’re getting close. Beta testing is progressing well, and based on feedback from our engineering team, we’re anticipating another 4–6 weeks of testing before moving into production. Please note that we do not have horsepower figures or pricing available at this time. Attached are screenshots featuring feedback from a few of our Banks Test Pilots on the 2024+ L5P Duramax Derringer, shared in our Duramax Facebook group.

Thanks Steve for the update!
 

Curiously will the intake and exhaust share the same roll out dates as the Derringer or will it be a phased roll out? 
 

Thanks!

@davidm767 I have updates for the intake and exhaust as well. The Ram-Air intake is in its beta-test phase with about a dozen Test Pilots. See below. Currently, we are ensuring that the new mass airflow intercept module and tubing we have developed function correctly. Please expect it around the same time as the Derringer.

The Monster Exhaust has been pushed back by about six months. We have all of the tubing sorted; what is needed is a piece of electronics to help intercept the computer so the truck does not freak out. The truck is sensitive to any changes in change with exhaust even after the DPF.The development time for materials and programming is going to take us a moment. We have tried tirelessly for the last few months to try and make the exhaust work by itself. Unfortunately, it will not work without electronic intervention.

Steve, I already bought the data idash pro, will there be a version of the derringer without the gauge? Looks like on the 23 it only comes with the gauge.

The Derringer for the 2024+ L5p, when offered, will have a kit option for those who already have an existing iDash Pro just like other Derringer kits.

It’s finally out! Both the Derringer and the Ram-Air are available to purchase!

Yes, finally! It is important to note the Ram-Air intake will NOT work for the 2025 model years, only the 2024. GM added a PCV sensor for the '25 model year. It has to do with ever-tightening emissions. The forthcoming Ram-Air Intake for the '25 will include both the Banks Air Mass Control Module which plugs into the MAF sensor, and a PCV sensor module. These modules are what allows us to flow greater air mass. Meanwhile, all other intake brands are stuck with stock airflow. Stay tuned for a release date.

Got my intake and loving it! Any update on the exhaust or when the derringer will be CARB compliant?
