If ever auomobile engineering goona change its technology

In summary, the pressure of the piston in the suction stroke should be around 20 inches of vacuum. Increasing this pressure could provide some benefits, but it can also cause harmful pumping losses. This vacuum is created by the restricted air flow caused by partially closed butterfly valves. Turbocharged and supercharged engines have a constant pressure in the manifold, eliminating the vacuum. Diesel engines do not experience vacuum at all. It is unclear what specific technology is being referred to and why it would need to be changed.

If you mean the vacuum value, then this should be around 20 inches and it's harmful actually and is referred to as pumping losses
nevertheless, there are some auxiliary components that utilize some of this vacuum, but this vacuum could be generated with an external device (e.g pump) therefor eliminating the harmful effects.

the vacuum inside the engine results from the restricted air flow by the butterfly that is partially closed
In a turbocharged/ supercharged engine there will be a constant pressure through the manifold which eliminates the vacuum from it altogether, also note that diesel engines don't experience vacuum at all

However, what "technology" excatly do you refer to and why should it be changed ?
