Who's the tuner? And why did you add Lu47's?

Consider trying your stock injectors and see if that clears it up?

Not sure what your future plans on, but if all you have atm is a cold air intake and manifold upgrade, stock injectors are more than adequate.

Did you happen to upgrade the throttle body with the manifold? And if so did PBD tune in for it?

I ask because when I see posts similar to this, the issues seems to center around the upgrade TB and the associated tune.
