I think that I've read that they are PFICO scores, which is a FICO score tweaked for the credit card industry. There are also specialized FICO scores for car loans. So it's a genuine FICO score, but if you pulled your TU score from this site, they might not match exactly.
The credit card and auto loan industries apparently felt a need for scores that were more predictive of how their particular borrowers would behave. For instance, the car loan FICO's give more weight to past history of car loan behavior.
