Overrevving when accelerating
Evo IX with about 44k miles.
Whenever I accelerate in 3rd, 4th, or 5th gear, my engine will jump from 3500rpms to about 4000rpms for a second or two and will then back down to where it should be. This only happens at WOT. If I ease it up to 4k, nothing will happen when I try to accelerate.
I tried to read up on this and I saw similar problems but with mixed comments on the issue. Is this my clutch slipping? A boost problem? I could really see it being either.
I have a boost gauge and it looks like I hold boost up to ~20psi but I am still planning on putting a boost leak tester together tomorrow to check that as well. Does this even sound consistent with a boost issue or should I just plan on changing the clutch out? I tried the "5th gear low rpm" clutch check and it holds strong.
Any thoughts or advice are greatly appreciated.

yeah bro, my cars got 21,000 miles! i still cnt belieeve the clutch is going.. i was in shock when this started happening. but since the day i bought it at 17,000 miles i always thought the clutch was a little slippy. but i never thought much of it cuz from driving a wrx everyone told me that evo clutches like butter compared to the wrx.. but i guess it was a lil F'ed up too.

Actually it was similar, but not the same - I would actually accelerate, but AFTER that the clutch would slip and RPMS would fall
It'll get worse as the clutch gets worn further, and it happens fast

I had many 4cyl turbo cars... launched the **** out of them... and only my 02wrx needed a new clutch... but it had 100k miles...
3 clutch, 16,000 miles??? take a driving course my friend (i mean that with as little disrespect possible)
