possible fuel cut

[kandt]

when i get to 5,500 rpms my car seems to loose power, its not fuel cut but i can't figure it out. Has anybody had this problem before? And what did you do to fix it?

Check for boost leaks..

its where dsm's start to drop power, first its turbo then its cams.

Could be also the ECU pulling timing due to excessive knock.
