From the time when I installed the CAI (going from a WAI) the car just rocks. CAI all the way. Since all my dyno's on the current motor were with CAI cannot compare really, but 90 deg+ summertime track time, really showed its benefits. Underhood temps in 140 deg plus range but he air at the end of the CAI was +10 F on avg above ambient. When ambient is in the 90's, I'd see a 40-50 deg difference at the intake down in my fender after running 5500-7500 rpm nearly flat out for 30-60 minutes. Coolant temps were only in the ~180 deg F range, has a big Koyo up front, UD UR pulley on the water pump.
Not very scientific but TT results showed the power I'd see on the dyno was being put to good use. Pulling significantly cooler air (it does warm up ~10 deg near the TB section) plus there is more at work there, throttle response is right now, and pickup to peak power in 2nd and 3rd was noticeably faster.
Butt dynos may tell rice lies, but the delta in lap times on a hot day between people I ran against repeatedly in 2009, cold days not so much, hot days I would put some serious gap on them. Not that many people run the full CAI for dual use cars, afraid of the water bogeyman I guess (I've driven for hours in torrential downpours, through standing water, never a problem - you really have to get into water up to the top of the wheel to start pulling it up the intake).
With the VE's better head flow I can only think with the right tuning it's only going to be better. What I find really strange is people running a stock ECU then testing Stock, WAI, CAI - no sh*t you won't see much difference if any, not with the conservative tune and timing pull-back of a stock ECU at you approach higher revs. That's a non-comparison test.
