Sct X4 Adjustable Settings

I have tires that are slightly larger in diameter so I use that to get the speedo closer. I have also adjusted the redline and idle rpm.

It's just a tool to load the tune, it works with no drama I really have no feeling one way or the other.

Now if you are talking about the actual tune that is another question. I have used the X4 to tune my Focus ST and now my Ecoboost Mustang. The canned tunes that come on the X4 from SCT make good power but they are not as polished as the tunes from Steeda and Unleashed that I have used. I am currently using Unleashed because his customer service is second to none.

I lowered the idle rpm. I was playing with 0-60 runs and raised the redline so I could get to 60 without shifting to 3rd.
