The hp gains with all intakes will vary. I can attest that with this VaraRam, my "azzdyno" could definitely tell a difference in throttle response. 
Cold air intakes, which is best?

For comparison
In the never ending quest for more rwp we decided to run a back to back test between 3 air boxes.
This is on my C5z with 383, 237/242 cam, ported fast 90, ls2 TB, Stage 2.5 heads, LG Longtubes.
Breathless Vortex
K&N FIPK
Callaway Honker
We started with the breathless and moved on down the line all intakes got 3 pulls with no tuning, all timing was set at 29* total and the af ran at 13.1-13.2:1 on all of the pulls
here are the dyno sheets
A comparison of all 3
Green callaway
red K&N
Blue Vortex
Here is the 3 vortex pulls
The 3 K&N pulls
The 3 callaway pulls
All tests were within 15 minutes of eachother start to finish

. That is so done as far as any valid criticism of a VRB2
. The install IS a pain though, as a first mod, and from what I've read here, it MAY be an issue in CA with the smog restrictions, so check that out first. The Honker by Calloway is 50 state legal, but it is around $500 plus shipping and the install price. The VRB2 can be found for around $300 new with shipping here on the forum, and maybe cheaper for a used one. That price for an install and a tune is ridiculous.A tune should be anywhere from $150 to $500 depending on engine mods and HP.That is what they get around here. Do some research first, and ask some other members in your area. A tune will definitely help with any of these CAI mods. Good luck.Don't listen to Ike
.Yeah, I know your car will smoke mine Ike, but I don't have the heads, cam, and gears you got from ECS.
BTW, the dyno sheets on the Vararam don't show the same results ( true performance gains) because it draws in COLD AIR at speed, which is not represented on a dyno with the car strapped down.

Is it CA legal? Search this database.

If performance is the goal-
Instead of wasting hours reading other peoples opinions - see if you can spend an afternoon at the local track. Corvette owners will glady share their experiances. You can see the the installed products and timeslips dont lie.

Being a fellow Californian, I suggest you purchase the Callaway Honker. It's the only CAI that is CARB legal in all 50 states. I have one and love it. Not sure you would really need a tune after installing it though. You may want to wait on the tune until you add a couple more bolt on mods. JMHO
Thus, my advice is to either get a legal intake or one that is easily swapped out when you need to.

Did you feel any difference after the install? Did you get a dyno tune? I month or so after I installed my VaraRam I got a dyno tune. I know the cars are supposed to tune themselves, but i was still running lean and knocking.

I have not gotten a tune, I don't track the car so as long as things are working well I am happy at present.

You need to hook those up and sell them for $100, if you dont I will. 
That is really nice work and it is basically a Calloway Honker sans the $420 price tag. Good stuff brother
I am interested in the filter surface size vs. the Honker or BPP Vortex filter? Do you know that info?

Thanks to everyone who offered sound and respectful input. I appreciate the different opinions, pictures, info.
I'm now told that I won't notice the 20 extra HP affored by the CAI. Not sure I believe that but maybe $600 is a little too much $ to spend just to capture 20 more HP. Maybe I'll just get the vette dyno tuned. I'm trying to be smart about the mod fever I have and know I have a lot to learn as I'm new to this and as a gal feel a bit vulnerable when taking the car in for work. I'll keep researching before I spend a chunk of change.
Thanks again
