Can new clutch slave cylinder make car less revvy?

Civic coupe vti 1999.

After I changed my clutch slave cylinder it seemed the revs seem to go up slower and I need to apply more gas now to prevent It from stalling and I shift gears later now.

I believe that if you have an old clutch it might be more revvy(slip) and if you never had a new clutch getting a new one would mak the car seem less revvy as it’s not slipping? Can a older clutch slave cylinder cause this symptom too and so what I am experiencing now is just how the car was designed? It feels more quiter and similar to a normal Car In low rpm than before the clutch Slave replacement were it was more revvy which I thought was how the car is meant to be and seemed nicer.

New clutch was pagid brand and original was most likely Honda.

Thing is I found the slave leaking recently prior to which I don’t believe it was leaking. So if the Slavs was worn, in what way could it be worn to cause higher revs or must it be leaking for this to happen?

Thanks
