I just recently purchased a SCT Livewire 9600. I have never messed with custom tunes but now I have the itch to. I have a 04 f150 5.4 4x4 with 3.73. I also have a Roush CAI. I mainly run 87 to 89 octane. What type of tune do I need or what all goes into a custom tune? How much do they cost and who has had good luck with which company?

 

Call Troyer performance. They did a good job for me.

 

More Power Tuning, 5 Star, unleashed, brenspeed, there is lots of places that write custom tunes for SCT. Cost will vary from place to place as you are basically paying for their time and knowledge to write the tune.

 

I had a good experience with JDM Engineering.
