Derringer® High Output

22 2500hd installed the power pac and wow it definitely not the same truck!

Pretty Easy Install and Great output

I installed the Banks Derringer with iDash on my 2020 L5P Duramax (emissions intact), and the overall experience was excellent. The install took a little over an hour, and I used the required 15-minute cool-off period to dismantle the driver area as instructed, which made everything efficient and straightforward. The instructions were fantastic—clear, well-sequenced, and clearly written by people who actually wrench on these trucks. Hardware quality is top-tier, with OEM-level connectors and a pod mount that looks factory once installed. Power delivery is smooth and controlled, especially on lower levels for towing, with improved throttle response. The iDash is the standout feature, giving real-time visibility into EGT, boost, MAP, fuel rail pressure, power level, and CEL diagnostics. This isn’t a CEL eraser, but it provides transparency and confidence by showing exactly what the truck is doing. Overall, Banks delivers engineered, reliability-focused performance that prioritizes longevity as much as power

Worth Every Penny!

The install was really easy with the provided instructions and videos. The only tricky part was reaching the injector plug, but it just took some patience. Overall, the install was a piece of cake. I originally was planning on only purchasing the iDash Pro to monitor DPF ranges for regen and manually regen when on longer trips. I’m glad that I bought the Derringer and Pedal Monster in the bundle package. The performance increase is huge!
