I don't buy Kool-Aid
Could be a bad fuel pump. Search it up. From what I have read its a e-z fix 
I would check my plugs. They could be bad not getting a good charge at the high RPM's.

Dear ALL,
I'm still having the problem. When I rev my rpm, it still hesitated @7500rpm (as though insufficient fuel for a 2 seconds) and then continue to climbing to 8500rpm and feeling lost of power.
It doesn't seem to be a mechanical problem. Do you think my ECU is the problem?
Anyone has experience this problem on 6MT JDM spec.
Need help urgently.
Thanks
