Launceston coach Mike Lewis says the threat of relegation from National Two South inspired his side to their 29-8 win at Clifton.
The result was their biggest win of the season, and just their fourth away from home as they moved up to 10th place.
"We did have a look over our shoulders and I think that might have been that little boost that has given the boys that bit of a kick on," he said.
"I hope it's not just a one-off, I hope it comes again," Lewis added.
"We've got something to play for, we're not just happy in mid-table, there are people chasing us," he told BBC Radio Cornwall.
The Cornish All Blacks are now 16 points above the relegation places with four games to go.
"That's done the boys the power of good, the confidence has rocketed," Lewis said. "It's the first one of the season where we've won by a comfortable margin.
"We've lost by a point seven times this season, but it was the character the players showed to get us over the line.
"It was almost like a weight lifted off our shoulders and it's the first time we've had that feeling that we've gone somewhere and turned over a team with confidence," added the club's backs coach.
