The Silverstone outfit saw both its drivers suffer pit-stop failures at the Malaysian Grand Prix but the duo had earlier done well to secure points-finishes in the season-opener in Melbourne.
In contrast, McLaren have seen Jenson Button and Sergio Perez achieve only as high as a ninth-placed finish and therefore the Woking-based outfit are six points behind Force India in the constructors' standings.
It is still early days in the new Formula One season but the VJM06 has demonstrated good race pace while Mclaren's MP4-28 has proven remarkably unreliable.
Scotsman Di Resta is therefore positive that they can preserve their lead over their rivals for a couple more races yet by virtue of some hard work and good race performances in the upcoming Shanghai Grand Prix.
"We know McLaren are a very strong team and they will develop well, so all we can do is continue pushing hard to try and stay ahead of them," the 26-year-old told the Force India website.
"It is important not to get carried away and to keep doing our job at each race. We looked to be one of the fastest cars during the early part of the race [in Malaysia]. It's a good sign for the rest of the season.
"The climate in China is very different compared to the first two races, but we've performed well in the cool conditions of Melbourne and in the heat of Malaysia."
