Force India insist they are "not sitting back" following their double points finish at the Belgian Grand Prix.
Adrian Sutil finished fifth at Spa to move ahead of Mercedes GP's Michael Schumacher in the Drivers' Championship while Tonio Liuzzi claimed one point.
Team principal Vijay Mallya says they are now looking to consolidate sixth place in the Constructors' standings.
"Yet again Spa was a good track for us, ultimately yielding a double points finish for Adrian and Tonio," Mallya said.
"These points were crucial for us in the Constructors' Championship, moving us 18 points clear of Williams for sixth, but it also showed that we're back in business for the second part of the season. The pace and the handling were both encouraging and, with similar configuration tracks coming up in Monza, Japan and Brazil, we're hoping that this performance can be replicated.
"Of course we know that the on track fights will intensify and it's not going to be easy to consolidate our position but we feel the momentum is with us now. Adrian and Tonio both raced very well and we've been given a real boost by the double points - we needed it after a couple of frustrating weekends before the summer break."
Next up on the F1 calendar is the Italian GP and Mallya says they are "cautiously optimistic and quietly confident" about their chances.
"But we're not sitting back based on this performance - we've been doing a lot of work back at the factory on the blown diffuser, and conducted a successful aero test last week to develop further," the team owner said.
"We will also use a low downforce package to suit the top speeds we reach in Monza, which is a further refinement of the Spa package. We're cautiously optimistic and quietly confident - if it all comes together I would hope we could show a similar level of performance and results to Spa, but there are so many varying factors that you just can't take anything for granted at this stage in the season."
