rev limiter

[Otto J]

i still am havin a problem with my car , it hits 5750-5800 rpms and it just stops dead the rev limiter is set in the 6400 rpm area, the heads are brand new champions w/correct valve springs for the cam i can send a log of a pass but as far as i see there is noting out of the ordinary does not go rich or lean when it happens, also the coil pack is brand new but not the module
any ideas?
thanks Otto
