Hi all,
I live in Flour Mound Texas. I have always loved mustangs. I was married for 19 years to a woman that said "NO"!! Well, divorced a couple years ago and finally got my toy! 09 S197 45th anniv. 4.6. I absolutely love it!! (a close second to my kids). Thing that is so fun is all the bolt...
I think my speedo reads too fast. I have an SCT tuner but not sure about the revs per mile settings or the spark settings in the strategy tune I'm running. I have 17 inch wheels. Can anybody help with the propper settings to correct speedo error? Also, explain the spark settings? Thanks!!
