Nico Hulkenberg is confident Force India has made a promising start to proceedings in Monaco, but has urged the team to build on its potential.
Hulkenberg was 11th quickest in the second practice session in Monaco and is searching for an upturn in form, having been unable to finish races in Russia and Spain.
"It was a very promising start to our weekend, on a day in which our priority was to get in all of our planned running," he said.
"Driving around this track is always a lot of fun as it’s a circuit that tests you to the limit.
"Even the newly-resurfaced areas have pretty good grip, so it gives you confidence as you drive.
"We ticked all the boxes in our plan and we were able to run on Ultra Soft tyres in the afternoon to learn about them.
"The feeling I got from the car is positive: there are a few tweaks we can make to get a bit more grip here and there, but the potential for a good weekend is there.
"It’s up to us to work well now and turn this promising start into a good result."
Team-mate Sergio Perez was eighth quickest but reckons further progress is required.
"It has been a good day with no issues and we’ve collected the information we need on all three tyre compounds," he said.
"I’m not completely happy with the car yet so I think there’s more to come."
