OTT on 4th and 5th Generation Toyota 4Runner

Year models available for tuning

We are tuning 4th Gen 2005-2009 4.0L V6 4Runner's with VF Tuner

AND

We are tuning 5th Gen 2010-2024 4.0L V6 4Runner's with VF Tuner


What changes can you make for my 4Runner

We have the following tuning capabilities

  • MAF Calibration for Large MAF and Aftermarket Intakes 
  • Remapping of Throttle Curves - Multiple Options
  • Rework of the VVTI / Cam Timing for more low and mid range torque while maintaining emissions at stock levels..
  • Ignition Timing 
  • Fuel Map Corrections
  • Supercharged Applications with Custom additions


2020+ 5th Gen 4Runner has full engine and Transmission Access

We are able to work both those complaints so there is no need, as is with some competitors, to also buy a "Throttle Booster".. If you have it, you can sell it! 

Some Calibration ID's are also not currently available, so just because you have a 2020-2024+ T4R, does not guarantee that it can be calibrated. So just give us a call and set an appointment and well do a read of your ECU at no charge. If its available we can then do your Custom Calibration at that time. You really have nothing to lose. 


Forced Induction and Aftermarket

Along with naturally aspirated, we will also be tuning Supercharged applications as well. 


Costs

OTT with VF Tuner on 4th Gen  2005-2019.  Starting at $450 


OTT with VF Tuner on 2020-2024 With Full Support.  Starting at $600 


"On location" tuning available for additional charge.  Pricing varies depending on amount of travel required.


Tuning will include the TSB upgrade to the latest Toyota ECU software, a $50 - $100 Value


What's the Process

Most base calibrations can be completed in about an hour. Custom Calibrations can take between 1.5 and 2 hours depending on truck setup and calibration goals. Supercharged applications will require additional time.

All vehicles must have fully intact emissions systems regardless if your current State of Residence has emissions regulations or not. No state is above Federal EPA guidelines. We will not 'Turn Off" check engine / Mil lights.
