I would have to agree with everything said. I have gone from acura and Honda to Volvo turbo and audi. And now diving into subaru I recently purchased a 04 forester xt which has been seriously built. Engine rebuilt ground up with new pistons, rings, valves, ported and polished. Full turbo XS rotated turbo system with huge TMIC. Huge header with screamer pipe and larger up/down pipes and custom exhaust with all cats removed and ECU replaced with sti one and re worked to throw no codes for smog. I met with the previous owner and the tuner and the two mechanics at the shop it was built at before I bought it. And it's been awesome and dyno sheet showed 343 HP 347 torque. And even those numbers are shocking when driving it u do have to be ready when you throw all that to four tires cause things in front of you get close fast! My debate on if I wanted more power was quickly answered. And while I may shoot for 10-20 more getting to 400 is really not necessary.
