Jackson Racing's customer service is garbage. I am sure they would blow you off if you brought the matter up to them. They are probably aware of the situation, but they won't do anything to remedy it like they should.

Between the lackluster HP gains, shitty customer service, cracking manifolds, or manifolds that leak castor bean oil, there are plenty of reasons to ditch that piece of crap and either revert to stock or turbo it.
