The Warrington Wolves gave their all at Salford but eventually ended the nine-match unbeaten run.
Wire was 18-6 at half time after Nathan Roebuck’s scores on the debit, replaced by Josh Thivilis and Riley Dean, all replaced by Deck Patton.
Wales all-time record try-scorer and former wire winger Rhys Williams scored a goal just before the break.
Elliott Care narrowed the gap further by trying to convert 12 minutes into the second period.
And eight minutes later, Gilmore closed the X-ray break to the level of things.
Inu opened the scoring with a last-minute penalty to give Salford the lead for the first time and eventually won.
