Force India says it will continue to develop its cars in a bid to secure fifth position in the championship as the midfield battle intensifies.
The Silverstone-based team edged out Lotus in the Italian Grand Prix, scoring 14 points as it moved back to fifth place in the constructors' championship.
Team principal Vijay Mallya, looking ahead to the Singapore Grand Prix, said that the team will have to score strong points to stay ahead of its rivals.
"With seven races still to go we cannot afford to ease up. The development of the VJM08 will continue and we need to take every opportunity that comes our way," Mallya said.
"The midfield fight for fifth place in the championship is likely to go down to the wire.
"Singapore will give us another chance to optimise the B-spec version of VJM08 as we introduce another small update package," the Indian added.
Sergio Perez feels positive about its chances at the Marina Bay circuit, where Force India has managed to score good points in its previous outings.
"We’ve shown in the last two races just how competitive we can be and I’m confident we can have a similar level of performance in Singapore," said Perez, having scored in all the four Singapore weekend, he has raced in.
"The team is pushing hard to bring performance to the car and we’ve still got developments coming through which will help us a bit more this weekend.
"I’m now feeling more comfortable with the updated car, which is a good sign for the rest of the year," he added.
