FYI - Prior to me putting on the after-market mods, my dealer said it was ok because the above mods do not affect the ECU.
I was going to wait until my first 3k service to bring it in, but I am going to see if they can take a look at it soon. I'll keep you posted with any details.
Please feel free to private message me on this matter.

Thanks - feedback still varies but seems to favor the "this is standard behavior until warmup", so you can see
my final decision on the matter here - I will keep that other thread (and my build thread) updated with any further developments.
Thanks again to all of you for the comments/feedback
