Welcome to Fish Tuning!

We manufacture Fish Tuning Advanced Dual (and even triple) CP3 Controllers for either Duramax or Cummins. And, in addition to our custom stickers and decals, we manufacture and sell CSP5 (temporarily unavailable), DSP5 (LLY, LB7, LMM/LBZ and LML), Keylock DSP5, Ford and LML switches and DSP2 switches. We also have spare parts as well as Ford (for EZ LYNK and SCT), LML and Cummins/Titan switches for EZ LYNK tunes. Coming soon: revamped DIGITAL switches!
