So by putting Cams in, we may not be seeing the gains that we could if we could go in and change some stuff in the ECU (wich only 05+ can).
So I think if you are going to be modding and want to get every penny worth, Piggyback or even stand alone EM would be something that you invest in. May not be one of the first, but maybe down the line.

Good to know and thanks for the info. EM is on the "eventually" list along with other non-engine related mods. I just wanted to see if I could get away with running cams for X amount of time before going EM, or if I had to do them together.
