Like the title says, it only does it when i'm revving, but not when i'm driving.

It started a couple weeks back, I was trying to do a 2nd gear burnout to warm up my slicks, but everytime i rev up to around 5000rpms it feels like i'm hitting a rev limiter , but i can still rev it pass 5000rpms. It only does it when i rev, but when i'm actually driving its fine. I just recently ran some honda top end cleaner through the motor and did a valve adjustment. I have no clue as to whats causing it to do this. I'll try to post a video later today.

Clutch slipping? Time for new clutch.

i dont think its the clutch, cause it does it even when i'm not in gear. i.e when i just sit there and rev to 5000+rpms.

 

u sure you dont have a s step in your ecu

 

i'm not really sure, but its never done it before. I'll try a different ecu just to make sure.
