On my cars colder air didn't add psi as I was ecu and waste gate psi controlled, but using your example "you may get 1 more psi," I don't know about you but my turbos psi ran me 15-20 more HP!!! I'll take that all day long to put the filter in a cai vs a sri.
But if you already have a IC you're not going to buy another one. And again it does make a difference no matter the IC! If its 60 degrees out, a compressor is 250 degrees, that mix goes through the IC, and out the other side pops out 65 degrees it makes a huge difference vs you put the filter in the engine bay where its 200 degrees, the compressor is again 250 degrees, that mixes and goes through the IC and out pops 90 degrees this time. 30 degree intake temps is huge in HP! I've seen 20-30 HP swings playing with this stuff on my WRX's while tuning them.

really a bigger intercooler doesnt do anything?
what exactly did you do to that WRX? i can tell you i gained an easy 50hp converting to a big FMIC on my turbo eclipse compared to the stock dinky SMIC, compared to the crap 10hp i got from a CAI on that car(i ended up selling it and moving to a SRI and i didnt lose power) hell my IATs also dropped big time stepping up to the bigger intercooler
also i dont know where you are getting those numbers but im pretty sure it only plays out with stock intercoolers(and even then it doesnt seeing as MCM put a CAI on a R34 and only gained 1kw and that was a stupid setup with the filter out in front of the dyno fan) but stepping up to a bigger intercooler will do much more for your car over a CAI but hey what would you WRX guys know, you all tend to use small TMIC over a FMIC
