Tsunoda first compared his struggle at Red Bull to driving in Formula 1 after a tough race at the Austrian Grand Prix.
The Zonodas finished the last drivers classified in the Red Bull Ring following a tough afternoon.
The Japanese driver received a 10-second penalty for colliding with Franco Corapined, which resulted in a change of front wing.
Tsunoda was the only driver who was lap twice, finishing 16th at the end of the race.
It continues to start the poor life of Zunodas at Red Bull, where he has scored points just three times.
Looking back at the race in Austria, Tsunoda said: “To be honest, the pace itself is also very poor.
“We are completely out of the level I want to be, where I want to be.
“It’s hard to believe I’m totally wrong, but the pace of our competitors is huge.
“We have to find out what the reason is, and for now it is really difficult to find a reason.
“(I) check the data. Compared to Max, it’s hard to see what I’m doing wrong there.
“Maybe I have to find a different approach, a different view. The pace of the race is like the first time I’ve been driving in Formula 1! The Delta is like that!
“It’s hard to believe I’m wrong, and I raced strong in another car at the beginning of the season.
“It’s the same car – a Formula 1 car – so I have to find out what the reason is.”
Horneda condemns the collision of Corapinto
Tsunoda was pleased to hold him responsible for his conflict with Korapinto.
He added: “That was my fault. I’ll apologise to him. I’ll give a massive apology to the team, and also a massive scale about how I took part in the race. It’s unacceptable.”
Red Bull boss Christian Horner described it as the “terrifying race” of the Hornada.
“Yuki had a terrible race. I was wrong in the first quarter. His first run was fine.
“I then drove through traffic and couldn’t pass, so I picked up a penalty. It made things worse.”
