Hi, and welcome to the forums!
All 3 CRAs use a different version of the FICO formula which, even with an identical report, would have different scores.
I'd figure out what's good and bad on EQ and use them as a basis for bring up your scores.
Also look at the 3 reports side-by-side. If you were to pull them on the same day, and the scores are different, there could be subtle differences (e.g. avg acct age, utilization, acct status, lates, etc.) that could also offset the scores. However, 30 points is not that much (relatively speaking).
