Welcome to the community!
I just picked up my Ultramarine 2013 FRS about two weekends ago from the dealership with about 38k Miles, nothing feels better than waking up and seeing that beauty sitting there.
Welcome again bud, there's an awesome community here that I've come to find and I'm sure that if you need anything people will come to aid.
Also, I didn't read much of the replies but just in case nobody else gave you the answer to the torque dip, You'll need a new exhaust system / header i believe, not something I've looked into a ton myself yet
