Red Bull were pleased to leave Monaco with a decent haul of points and no engine penalties, but it could be a different story in Montreal.
Having battled midfield runners for double points finishes in the opening five races, the Milton Keynes squad was finally able to mix it a bit further up the track on the streets of Monte Carlo.
Daniel Ricciardo and Daniil Kvyat qualified fourth and fifth fastest respectively while the latter went on to claim a career-best P4 finish with his Australian team-mate one place behind.
"[Monaco] is the least power sensitive of all the tracks on the calendar and I think we managed to optimise what we've got; Renault did a good job of getting the best out of their current package and I think we got the best out of the chassis and drivers," team principal Christian Horner said.
"Fourth and fifth with two Mercedes and a Ferrari ahead is – we beat a Ferrari fair and square – is as good as we could have hoped for."
Next up is the Canadian GP and Horner admits they could be forced to take engine penalties following their woes earlier in the season with their Renault power units.
"I think Canada is a much bigger challenge for us than here," he said. "We managed to score a good amount of points. It's 22 points we managed to take out of Williams so a positive result, it's the maximum we could have expected and Montreal is going to be a much different challenge.
"I think the fact we got through without any engine issues at all is a step in the right direction. We've now got to evaluate what happens in Montreal, whether we take a penalty there or not, it really depends on the state of these engines after this race – it's not hard on the engines round here and I think it's something we'll have to evaluate this week."
