Welcome to Fish Tuning!

We don't tune anything, but we DO manufacture Fish Tuning Advanced Dual (and even triple) CP3 Controllers for Duramax or Cummins and BMW. And, in addition to our custom stickers and decals, we manufacture and sell Cummins switches (for EFILive® and MM3), DSP5 (LLY, LB7, LMM/LBZ and LML), Keylock CSP5, Cummins/Titan EZ LYNK®, DSP5, and Ford (for EZ LYNK® and SCT) as well as DSP2 switches. We also have spare parts, EZ LYNK® Titan Unlock cables, Fuel Injector Connectors and more. Coming soon: revamped DIGITAL switches!
