SpaceX plans to boost Starship raptor engine performance, Elon Musk unveils
Elon Musk recently replied to a tweet that at least 15% of the Raptor performance will be improved and the number of engines installed on Starship by 50%. These updates come when the Starship is being developed and modified for its debut launch. To be launched with Super Heavy Booster, it was to use a boost variant of greater thrust vector control (TVC) for a better thrust.

A wide throttle range of thrust is to be improvised for the Super Heavy Booster. On June 3rd, there were some photos clocked about 3 new Raptor engines being located in the Boca Chica Starship factory. And two labels on the two engines can be seen as RB3 and RB4. Predicting that they completed testing in McGregor, Texas.
