Verstappen was complaining particularly in the qualifying session on Saturday regarding the turbo-lag his RB15 was getting. Due to the lag, there was a delay in the speed produced from the turbo.
Red Bull team principal Christian Horner already said that it was "Honda's problem" regarding Verstappen's car and the Japanese manufacturer is not taking this issue lightly at all.
"We look at which calibration needs to change and how much it needs to change to improve it," Tanabe said. "We talked to Max about when he feels this delay. It is not something that causes a reliability problem, but this is a major technical problem for us."
