    problem solved!!

    it was a vacuum leak underneath my weiand ls6 intake manifold! never buying a weiand product ever again (they use a block off plate in underneath the weiand ls6 intake manifold, guess they should of stated "apply sealant on gasket" not talking about contact between heads and intake.... used brake cleaner to check for leak and once i sprayed underneath the intake a huge white smoke came out from the back of the exhaust.
