Exeter City manager Paul Tisdale says he is "delighted" at his side's
The Grecians recovered from going a goal down early on as Jamie Cureton scored twice, including a late winner, after missing a penalty.
"I'm delighted. Two away wins against Bradford and Gillingham in the space of four days," Tisdale told BBC Devon.
"It was a big ask to go a goal down against the league leaders in the first five minutes and come back as we did."
The victory moves Exeter back into the play-off places having won three of their last four matches.
It is a stark turnaround having gone six games without a win before their current run.
That change in fortune has coincided with the return to full fitness of attacking midfielder Alan Gow, who scored an excellent free-kick at Gillingham.
"He plays his game extremely well and my job is to allow the team structure to allow him to get the best out of what he does," Tisdale added.
"When we need him, it's his responsibility to step up and he does that fantastically well."
