Long story short,Ford doesnt know how to correct my speedo for 4.10's.
So we worked it out for them just to buy a DM speedcal ( well hopefully..not gonna get to detailed on it),but the Ratio chart they provide for the settings only list up to 3.27's gears as stock,well mine were 3.55's.Will the DM SpeedCal work and if so how would I know what settings to use.
I have emailed Dallas Mustangs but just wondered from anyone here that has had this issue.
Here's the link to the ratio table
