Alright - little update.
I just got off the phone with Scott at Relentless (my car is there getting re-tuned) and they're pretty sure it started to slip on the dyno. I also just got off the phone with SGP and they are also saying it sounds like the trans could be slipping. I guess my best bet is to take it to a transmission shop and get them to check it out.
Any other advice would be helpful.

Are they going to diagnose what is actually failing, it may be the clutchpack/bands inside the tranny that have gone bad and need to be upgraded. Your VB may be fine but the tranny internals have given way.

Thats what Mark at SGP said. The only thing is, the trans was completely fine before I did the VB upgrade. So I don't understand how it can go from 100% okay, to all of a sudden damaged if the valve body doesn't have something to do with it all.

Yours may have been close to that point when the VB was installed. Not saying the VB helped speed up the process but eventually it would have slipped.

If the tranny fluid gets too hot, the 5AT should go into "limp mode", which would have been evident - I assume this did not happen.
Well at this point, it's all speculation till the tranny is apart. At least high performance rebuild kits exist now...
EDIT: let me add the caveat that I have only driven on the street and my boosted experience is minimal. I have talked to Ron (roncfpz) and he did run into problems with just one tranny cooler on the track (but I don't think he had his up front directly in the path of airflow) so he might be running two in parallel now - you could PM him if you think heat was the culprit...

Also, as one begins to add larger or multiple coolers you begin to stress the trans fluid pump and decrease line pressure which "softens" the shifts again. It's important to get the right balance for the factory trans pump. It would be interesting to hear from SGP or GTM as to possible upgrades to the pump.
Good luck.
