I have an 08 WRX that has been exhibiting some weird behavior under hard acceleration. If I take my foot off the gas and depress the clutch when the RPMs are above 5k or so, sometimes the revs will shoot up. This happens the second I depress the clutch, and if I keep the clutch depressed, the will fall back down again. If I wait an extra little bit after releasing the throttle, this doesn not happen. Has anyone had anything like this ever happen before?
#Revs shoot up after depressing clutch while high in the rev range.

Does it have stock ECU software? That sounds like a throttle blip feature
winged jetty
Yes, it is tuned with ECUTEK
tidal sparrow
Yeah it's throttle blip
Allows for quick downshifting without touching the gas pedal

Interesting. My issue with it is that I was doing an Autocross event last summer and on a couple of the downshifts, it pushed it past the redline.
which seems like a very bad thing while the engine is not under load
Since then I have been much more conservative while shifting for the most part
but it still happens occasionally

Mine is only set up so it activates only when both brake and clutch are pressed

I bought the car in 2020, and the previous owner told me it had throttle blip
but I have actually never noticed it doing it when I actually was downshifting
and then last year I started noticing it on hard acceleration
I thought that perhaps it was a vacuum leak, so I smoke tested the engine, and found that the turbo inlet was torn. I replaced the turbo inlet with a perrin, but noticed it again today doing a highway pull
I have considered getting the ECUTEK dongle so I can get more information in real time, but if I wanted to do any further mods/tuning to my car, I would need to move away from ECUTEK due to the closest ECUTEK tuner being 5 hours away.

Someones increased the rev limiter then

Someones increased the rev limiter then
Or there's a massive skill issue in downshifting here
vestal matrix
Yes or that

Rev limiter cuts off hard at 6.5k outside of this case.
perfectly willing to accept it is a skill issue though
If that is the case.
