EcuTek Custom Tuning — 2022+ Toyota Tundra 3.4L Twin‑Turbo (V35A‑FTS)

Toyota Tundra V35A-FTS Custom EcuTek Tuning | PhoneFlash

“Base maps” are quick wins, but they aren’t bespoke. Our V35A-FTS tune is built from your logs and configuration, then refined for smooth torque delivery, better throttle modulation, and smarter shift behavior for daily use and towing. We design for repeatability under heat-soak and load—no “one-pull wonders.”

Supported platform: 2022+ Toyota Tundra i-Force 3.4L twin-turbo (V35A-FTS). 

Proven approach

• Optional Flex Fuel with ethanol content learning*
  *Flex hardware required; feature support may vary by vehicle.
