Scotland captain Jamie Ritchie said "we have got a lot more in us" after Gregor Townsend's team routed Wales 35-7 at Murrayfield.
Wales were no match for their hosts in Edinburgh on Saturday, as Scotland cruised to a bonus-point win that sees them join Ireland at the top of the Six Nations standings.
George Turner went over in the first half but Ken Owens crossed for Wales, who should have gone into the interval on the back of a second try, only for Rio Dyer to squander a golden opportunity.
Scotland made Wales pay – Finn Russell combining twice with Kyle Steyn before Blair Kinghorn and Matt Fagerson drove through late on.
Their winning margin of 28 points marks Scotland's biggest victory over Wales in Test rugby, with the only other time they have beaten them by more than 20 points coming back in 1924.
Next up is a trip to reigning champions France on February 26, and Ritchie is hoping for more from his side at the Stade de France.
"It wasn't perfect but we did enough to get the job done," he told BBC Sport.
"We have belief that if we play to our best we can beat any team. It wasn't perfect today, we've got a lot more in us. We're looking to improve when we go to Paris, definitely."
Saturday's match marked the first Test at Murrayfield since the death of Doddie Weir, who passed away in November.
Scotland were presented the Doddie Weir Cup for their victory, and Ritchie said: "We're delighted and I'm glad to be holding Doddie's trophy.
"The first game here without him, we miss him so much, I'm just glad we have our hands on this. We're so delighted, I'm a bit all over the place at the moment – a bit emotional. I'm glad I could do this for [Weir's widow] Kathy and the boys."
Russell was the star of the show for Scotland, teeing up three of their tries and kicking 10 points.
He has now provided 10 try assists in nine Test matches for Scotland since the start of 2022, more than any other player from a Tier One nation in that period.
"I was just doing my job – making other boys look good," Russell joked after becoming the first Scotland player to register a hat-trick of assists in a Six Nations game.
"It showed the continuity in the squad. The boys were all on the same page and it allowed us to attack how we did today."
Scotland have won back-to-back games to start a Six Nations campaign for the first time, with the last time they had managed to triumph in their opening two games of the Championship coming in 1996, when it was the Five Nations.
Russell added: "Great game, great result for us. We knew we'd struggled before after the first games to back it up, and I think the boys put in a good performance today, which was great to have back here at Murrayfield."
Wales have lost their opening two games, conceding at least four tries in each match. It is the first time they have done so in back-to-back Six Nations Tests in the same year.
"When you're winning and you have that momentum, it's hard to lose. The flip side to that is the same," said captain Owens, with Wales having won just twice in their last 10 Tests.
"We've got to work hard next week. There's plenty of experience but plenty of youngsters coming through. There's new coaching staff, new players coming in, we just need to work hard.
"Turn the corner hopefully, against England, we've got to grind out a win, find a win and build that momentum. There are positives there. People are going to say there isn't but we believe in what we're trying to achieve, we work hard and try to deliver."
