UTV TFI Power Box Tuners

TFI Power Box fuel tuners for fuel-injected UTVs. The Power Box plugs inline with the factory harness, no laptop and no dyno, and adjusts fuel across three ranges so an aftermarket exhaust runs right instead of lean. Find the box for your RZR, Ranger, General, Maverick, Defender, Talon, Pioneer or Wildcat.
