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!

Although we do offer spare parts and information online, please note: we are a manufacturer and do NOT sell our switches on our website, on Amazon or on eBay. If you are a reseller and interested in purchasing our switches for resale (not for personal use), please contact us at (310) 499-0989 Monday-Friday after 10AM Pacific Time.
