I recently removed my crower stg 2 cams/cam gears as well as my FocusSport 4-1 header and replaced them all with the OEM counterparts, but I left my ported head. I also still have the AEM CAI, FC TB, and ported 2000 on the intake side.

Now when I drive I feel like the car hesitates/stumbles at WOT in 2nd gear. Is this due to the ported head still being on there??

I have 2 DTC's one for EGR (removed) and rear O2 sensor (race header). But I did not have this stumbling problem before I removed the cams/header.

Could my timing be off?

Could be timing, but I think it's most likely A/F ratio. I had a similar problem that was corrected once I got chipped. I don't know the specifics, so I'll let one of the A/F gurus do that.
