Unlock true on-the-fly control of your 2006–2010 LBZ/LMM Duramax with the Fish Tuning DSP5 Switch (part # FTDSP5LBZ/LMM). This five-position switch works with EFILive DSP5 tunes so you can change power levels instantly from the cab—no laptop, no reflashing, no waiting.
Key Benefits
- Instantly select between five custom tunes (economy/stock, tow, daily, performance, or race-style maps)
- Designed specifically for 2006–2010 6.6L LBZ and LMM Duramax engines
- Simple DIY installation using the included pins and wiring (Gray/Black wires to ECM Connector 1, pins 46 & 54)
- Includes the switch, aluminum knurled knob, 1-5 position decal, and installation hardware
Important: Tuning is not included. Your truck must already have EFILive DSP5 (switch-on-the-fly) tunes loaded for the switch to function.
Perfect for owners who want the flexibility to run a mild tune for daily driving or towing and then dial up power when the truck is empty—without ever plugging in a programmer.
Fits: 2006–2010 Chevrolet Silverado / GMC Sierra 2500HD & 3500HD with 6.6L Duramax LBZ or LMM.
