Hosts Pakistan meet Hong Kong in the opening Group B encounter on Tuesday. India, also in the same group, play Hong Kong on Wednesday.
"It's not about we are favourites, you have to perform to your potential and keep the momentum to win the tournament," Dhoni told a press conference ahead of the opening of the six-nation event.
Bangladesh take on United Arab Emirates in Lahore on Tuesday in Group A, which also includes defending champions Sri Lanka.
The top two teams from each group will qualify for the super league, in which each side will play each other to decide the July 6 finalists.
Dhoni-led India upset world champions Australia in the tri-series finals held in Australia earlier this year.
But they came crashing to earth after losing to Pakistan in the final of a tri-series tournament in Bangladesh earlier this month.
"It will be important for all the sides to perform well to win this event," Dhoni said.
The Indian skipper, who batted down the order in the final of the Bangladesh tri-series, said he would decide on his batting position after seeing what kind of start his team made.
He told reporters that the international calendar was getting increasingly crowded with the explosion of Twenty20 cricket.
"The international calendar is getting challenging. There used to be Tests and one-day internationals, now its Twenty20 as well and there are 365 days in a year so it's getting tough and demanding but you have to adjust," said Dhoni.
He said that allrounder Irfan Pathan has suffered a side strain and was likely to miss Wednesday's match.
"It's not a concern but Pathan has a side strain and we may rest him in the first match but he will be OK by the second game," said Dhoni, referring to his team's crucial match against Pakistan on Thursday.
