Both the TU and EQ scores are from here, right? Ignore the EX score assuming it didn't come from a lender. Your EX FICO could be much higher or lower.
It's normal for the two EQ and TU FICOs on here to differ. In fact, it would be a rare oddity for the two to match since the formula differs between the two. However, 84 is beyond the norm. Can you say with 100% certainty that your EQ and TU reports are EXACTLY the same? Are you certain you have the exact same accounts? Are you certain the balances are exactly the same? Are you certain the payment history is exactly the same? Are you certain you have the exact same inquiries on the same date(s)? Are you certain all of your accounts updated exactly at the same time based on your last pull? Do both TU and EQ have the same reported dates? Do both show the same status? Do both show the same "worst delinquency"? Same length of history? Same AAoA? Same util?
Any differences in the above can easily throw your score off by 84 or more depending on the change.
