The win keeps Exeter in touch at the bottom, although their hopes of staying up remain slim as they are five points adrift of safety with two matches left to play.
"We can only look to win the next game, but we're playing very well and have scored nine goals in the last three games," Tisdale said.
"We have continuity in the team, which we have not had for a long time and it provides us with a chance of winning the game.
"We have a tough game at Carlisle and they're going for a play-off spot, but you just don't know. Everyone is feeling the pressure, but we have nothing to lose. We'll give it our best and see where that takes us.
"I'm delighted with the win and the way we played. We are putting some form together and I am delighted with his we are playing when it would be easy to give up and lose faith."
