    can you tune your truck for certain cold/ram air intake systems


    • SCT has many tune files available for a myriad of intakes, however, you may also use the tuner to allow a dyno tuner to calibrate your vehicle with your intake.

    I own a version of this tuner from my 2007 Mustang V6. Can that tuner be reprogrammed to use on my current 2011 F-150 3.5 Ecoboost? Cost?


    • The device would need to be reset by SCT and a recalibration would be needed. Please contact SCT for instructions and a walkthrough of what you will need to do to recalibrate with a new vehicle.

      The big hype

      This product does do a speedometer delete. And it does what it says it willl do. But get ready to spend some money on a mechanical bov the ebov just keeps blowing off especially when going uphill. ISCT needs to redo program for ecoboost or I can look for other programs to download on there programmer. I mean we should be able to control when the ebov blows off.

      Great tuner.

      The connection of the TUNER and downloading a tune was quite simple. The difference in the performance of the truck was immediately noticeable. I may in the future load other tunes but right now I am pleased with the performance.

      Open the box, update the tuner, can take 10-15 to update on the computer. Plug it into your OBD II port and its that simple, def feel a change.
