Had a buddy check it out... he says he can't hear anything out of the ordinary but that the engine was a bit noisy however nothing he would find an issue. He asked if it was missing or having any other symptoms which i explained the vibration at 2300 - 2500 RPMs. He mentioned that almost every car has a slight vibration around those RPMS and sure enough my 1.5L ecoboost has a similar vibration although not as pronounced. It's also over half the displacement smaller...
Final verdict he said is that I know my engine best, if I am hearing something that he can't hear then it could be something in the extremely early phase of going out, but that a lot of these motors have different noises. If the car is running well, no loss of power, no other real symptoms besides this noise I am hearing that even if I took it to Ford they aren't going to touch it. Best bet is just keep an ear out and see if the noise gets worse or not.
He seemed to think it isn't worth putting much more effort into... his opinion is that it sounds just like every other ecoboost he has worked on...
He is an ASE Master Mechanic that worked for Ford for a long time. Now builds small and big block Race motors for people in his barn. We've been friends since I was in middle school, I tend to trust him.
I did ask him about the possibility of the torque converter going out... he did a few tests on it and said it felt fine. He reminded me that if I am tracking it, that once those transmission temps get to 209ish they can start to act sluggish and engage/disengage different than normal... that I need to let it cool down before getting on it...
So for now, I am going to table this unless something else pops up...
Now to wait for Julio to respond about why my meth pump keeps requirement me to up the voltage to keep pressure...
