It puts out 2 different fako's because it is 2 different scoring models. Save your money and only use
Myfico.com or
equifax.com for real FICO's
Myfico is the only one that will give you your real TU, EX and EQ FICO score period.
Equifax will only give you their real FICO score but WILL NOT give you the Fakos from TU and EX.
And most of the time banks and such only look at Equifax because they do use FICO.
Hope this helps.
