That said, car feels amazing, boost never drops, it starts at 23psi by 5000rpm, and get to 26.5psi by 7800. Giving a progressive power feeling all the way to redline.
That tuning method is only valid for motors that have weak rods, which the EJ207 doesn't have. Go to some other tuner that really knows Subaru engines, because the one you went to doesn't.
