Default Question after GTP Stg. 2+ install

Well I've got my GTP stg. 2+ heads (241 castings on .040 cometics) on finally along w/ my Torquer 2.

Now my question, there is a noticeable "lag" from 2200-3100, but after that it wakes up and pulls fairly well, but not like I figured they would. Nothing is wrong w/ the heads, they flowed 323 @ .600 and somewhere in the range of 12+ cfm throughout the entire range over my other option the PRC 5.3 2.5's. Did the heads alter my tune so much to cause this, or are my heads out flowing my cam? Just trying to determine if a tune will indeed wake my car up, or if my heads are potetially out flowing my cam.

Posted in the PCM section too because it deals w/ both....i think

You just need to get the car re-tuned

Anytime you change a part on the engine like heads, cam, headers, intake, etc. I would suggest getting it retuned.
