No real nasty noises on startup...I need to run the car more now that it's back on the road. A light tapping right off, but goes away pretty quickly, before the SAI shuts off...my Explorer Ecoboost 3.5TT does the same thing.

Main concern was what you heard and described as the cam advance...I don't notice that on my 2.7T.

Thanks again for your input, I'll PM about tuning, thanks!
