Ferrari have set their sights on third and fourth in Malaysia while they also believe they can reduce the gap to Mercedes if they "get everything right".
The Scuderia made an impressive start to their 2015 campaign with many believing they are now Merc's closest challengers after Sebastian Vettel finished third behind Lewis Hamilton and Nico Rosberg at the first race in Australia.
While everything went flawlessly for Mercedes, Ferrari had one or two issues and technical director James Allison believes they can edge closer to the pacesetters if they improve.
"Let's assume Mercedes don't make a mistake, with the gaps we saw in Melbourne we expect them at the front," he said.
"But we think we can be a fair bit closer to them if we get everything right – we didn't get everything right in Melbourne and in Malaysia we hope to, so I hope we can put our car in a strong third and fourth on the grid."
One of the biggest challengers for all teams in Malaysia will be the heat on and off the track.
"Sepang is obviously totally different climate but the track is not so different, we look at tracks normally in two main ways: how sensitive they are to horsepower and how sensitive they are to downforce," Allison said.
"If you look at Sepang compared with Melbourne in those ways then Sepang is very similar, so a car that was at a certain level of competitiveness in Melbourne should really inherit that at Sepang.
"The difference is Sepang is very hot and is therefore a challenge to keep the car at the right temperature and also the tyres at the right temperature, so that is a bigger deal than it was in Melbourne."
