blacktop 20v 7age wont rev past 6500rpm

[Jinxd]

hey guys having some problems, maybe someone else has had this problem before?

engine setup:
7age 20V blacktop head. recut cam sprocket etc. stock AE111 ecu running COP's
OEM coil and igniter connected, speed sensor connected. O2 connected, sta wire connected etc. Ecu throwing no error codes.

The problem:
car starts runs and idles fine, when revving the car on partial throttle it winds out to 8400rpmish no problems.
when you put the car on wide open throttle it gets stuck at 6500rpm like its hitting a brick wall.

things ive checked.
changed over fuel pump, changed injectors, ignition timing is good etc im thinking it has something to do with the cop's
does anyone have any ideas, on what could be causing this? i know there was a thread on Club4age but since they had a crash i cant get to it.
thanks guys

hi there.. given that it makes it to 8400rpm on partial throttle, but has issues on W.O.T, have you looked into possible faults with the TPS?
if you have COP what's the oem coil for?
