I would do a quick search for a leak somewhere, if it is still idling at the rpm as it always has I would check for leaks anywhere between the turbo compressor and the throttle body.
I know that my turbo is at the limit of it's efficiency range on 20psi on my engine so I am not surprised that I see a slight drop in boost (of 1 to 1.5 psi) once the air temps increase form below 10 to over 25.
I wouldn't have thought that 14psi would have your turbo's near their limit and I assume you run a decent intercooler too? As even if you can maintain the exact same boost levels but in one case your engine is taking in nice cool air and in the other case it's taking in hot air the cool air will make more power and more importantly feel better to drive.
Edit: Saw in your sig that the IC dimensions and that should be doing a fine job.

ill check again for a leak but i dont think there is one there...
at 14 psi its at the top of 1jz's turbo's safe limit i guess...
The intercooler does an awesome job.. also ive got no shroud around clutch fan atm and blows onto both ic pipes and the pod.. so that wouldnt help matters on an already warm day.
I was amazed to see it only making 12 psi aswell.. ill give it a good look over tomorrow morning
