Not much better luck with the other supplier that I ordered from simultaneously. Researching alternatives while I am waiting because this is getting ridiculous.

OK...so I just heard about this and I'm a little confused. First pls add me to the list...CAN I JUMP TO THE FRONT SO I CAN GET MY 370/MP122 RUNNING? I bot the 90mm kit from WCCH and am using their J-Tube & TB. Richard told me about the flap issue. I assume I'll need this fix? What does Maggie put on their MP122 kits...do they have the same issue?

You will need to get this fix inorder to get the throtle blade to open 100%. You should of already gotten a 2002 TAC module and harness adapter inorder to use the 90mm. When you recive this harness adapter from DrX you will reuse your stock TAC and remove the other one. All the 90mm guys have this issue,Maggie or not.

OK...spent some time on the phone with Maggie, and they're telling me the engineers say its a simple MAP issue. 
As I'm only just now aware of this and still coming up to speed that sounds as reasonable as anything else. They say that the controller in the TAC/PCM program reads too much air/airflow and shuts the throttle causing the motor to puke. If thats the case, then once I plug in my NELSON tune with appropriate MAPing and specific parts spec, this whole thing shudn't be a prob...

**Either way - PLS MAKE SURE I'M ON THE LIST**

Throttle position data is a significant factor in engine/transmision management, so incorrect data can result in some undesirable behavior.
