Default RPM goes up after pressing the clutch

Is it normal to have the rpm's go up a few hundred after pressing the clutch.
For example, you're driving in 3rd gear coming up to a stop. You let off the gas and press the clutch does your rpm jump up by about 300 rpm before going down?

im not sure if my rpm goes up from stepping on the clutch but my rpm drops after i rev the car. Its drops lower than usual and gets close to stalling. I got the pop charger and i jus installed the nismo exhaust. How do i fix this? I was thinkin of unpluging the battery and reset the ecu.

my ride does the same thing, but only during start up and cold mornings.

What ever happened to the days of a good ole throttle cable, today 90% of cars are throttle by wire, a servo motor opens and closes throttle bodies, one more part to malfunction.

oh. i noticed it too. i always thought it was b/c of the flybywire. Takes time for the motor to close the buttefly in the TB so since the engine is free of the drivetrain it revs a lil.

if you shift a little slower, it has a little rpm jump, but if you shift fast, you won't see it jump.
