So who thinks their intakes are messing up their car??

Hardware store. Bring your intake in with you and just match it up.

All I can say is that I have never seen any reports of compressor surge issues with Hahn's intake, Injen's intake, or Dejons. All skew the fuel trims. That I can easily fix but this surging the AEM ntake causes is not so easy to get rid off. The only real big difference between Hahn's intake and AEM's is the MAF placement.
I could block off the MAF location on my Injen pipe and do some experimentation with that adapter. Move it closer to the filter maybe and log some runs? I would have to extend the MAF harness but that shouldn't be a big deal.
Testing various locations for the MAF is something I would expect Injen would have done, but based on the issues being reported, I'm not so sure.

Term2, keep us updated with what you find out about rigging something up. I'll have to come see you again if it's promising.

I have an unopened MAF adapter that I bought from the local auto parts store, I was going to build my own intake at one time but thought better of it. I still have the adapter.
I could block off the MAF location on my Injen pipe and do some experimentation with that adapter. Move it closer to the filter maybe and log some runs? I would have to extend the MAF harness but that shouldn't be a big deal.

Well I will log the Clear Image intake once it's on. It's gonna throw fuel trims off definitely, but the question is, by how much.
According to Dan, he mentioned on the stock tune it hasn't caused any side effects, but we don't have any logs for proof.

Did you get the CAI or SRI?

It seems like moving it closer to the filter but further from the engine is the worst thing to do in this case. My car had a few FT issues especially once it got hot with my Dejon SRI but it never caused any surge. I can fix the fuel trims but I have not found a fix for the surge.
I understand that the FTs can be tuned out, but from the evidence gathered by Tofu, a recalibration still results in a LOSS of power through a large chunk of the power band. That bothers me even more than some simple cold startup driveability issues and some part throttle surging.
Do you suppose it's possible that the power loss is something that can be remedied when additional fuel tables are discovered?

Understood. I'm not sure I've experienced the surge with my Injen pipe, but I do get some occasional bucking under part throttle. Maybe this is what you are describing.

Yes at this point. I am keeping my AEM for the elbow and I might eventually put it back on the car.

I wonder if there's a table that needs to be unlocked that has to do with "latency of MAF readings". In other words, the amount of time between the time the MAF makes a reading until the ECU knows it's time to act upon that reading.
What may be happening is that we've got the MAF/ECU out of sync with the engine when the MAF starts getting relocated.
