You know,.. I do but it takes a wile to get dusty.
If the car were clean ,and I drove it to the office everyday , 42 miles roundtrip on an industrial freeway with lots of 18 wheelers and construction ( my normal commute). It would take about 2-3 weeks to start collecting some dust.
Because its a test car , I have gone out of my way to try to make things break . To do so, I use the road less traveled. Maybe a better way to say that is the road you don't ever want to drive any Corvette down. Dust, pot-holes , rocks etc... a "Shaker". Even doing that, it takes a wile ,because nobody in their right mind is going to tailgate someone down a dusty dirt road in a Corvette .

How long have you had it like that? Does it seem like the heat is effecting the paint on top? Is it any louder?
I am also curious as to if removing the under hood blanket insulation will cause the hood to warp or if the heat will damage the paint. There has to be a reason why they put it there.

Removing the upper radiator shroud is a no brainer!
Its definitely blocking/holding heat in, and its really only channeling the top 5% of the radiator surface..
Removing the under hood louver shroud is also very beneficial!!
If you look and feel in between them from the top of the hood into the engine compartment, you'll see this is blocking/limiting some of the louvers, preventing and limiting heat to escape!!!!
Much better heat removal air flow with both shrouds removed for sure!!!

Well I installed my Vararam yesterday but had one part to put on today. Thanks Steve for scooting it out here. I really appreciate it. Rechecked and slightly tightened all the clamps and fittings, started up the Vette and drove around the block. It sure cleans up the engine compartment and if it works as well as the one I put on my C5 ( that was a real PITA to install) or as well as the one I put on my C6 I'll be thrilled! 
I'm sure it will. I'll drive it a lot more on our trip this weekend and hopefully no codes will pop up.

Removing the under hood louver shroud is also beneficial...if you look and feel from the top, (louvers into the engine compartment), you'll see this is blocking/limiting 3 of the louvers.

The Camaro's really got the shaft in 2014-2015. That center hood vent is totally blocked off except for a couple of small water drain holes.

I see an opportunity for a company to make a trim ring that will finish off the underside of the hood when the Factory Heat Blocker shroud is removed ...

We do recommend doing it after an install, however, I have put the units on numerous cars of different years without doing it and no light. If someone does get one, just drive it normally for 32 miles or less , light should go off. Assuming all connections have been checked , Maf harness etc..

Shrouds removed...
This will definitely improve heat extraction!!!
Just waiting for mine to arrive!
The only other thing I may do is put some foam insulation or electrical tape over the MAF connector even though its a water tight connection... Just a little peace of mind while washing! haha! I could also remove the clips for the hood shroud, but I decided to keep them on in case I ever want to snap it back in place...

Combined with a 160 Thermostat and turn the fan on earlier and it will work great for street use and drag racing.

Well,.... lets just say the entire Rear shroud and fan area needs a Re-design. Its fine for street use but not Med and High speed Road racing/Club racing. There is just no aspect of it that is correct.
The flow through area is in the wrong spot. The fan and fan shroud are not setup to flow High and Med speed air. Trap Hot air YES ,but not remove it.
As is, its setup to pull a vacuum from the font of the car using the fan. That's fine for low speed , but not if your running Nose to Tail down a straightaway.

VR Tech - when I view the video you posted, I can see a finger wide gap where the intake filter box mates with the frame on the fender (the tech doing the installation in the video actually runs his hand in this gap, and the edge looks like rough cut). Thought this was a sealed system?
Also, I attempted to install the aFe Momentum CAI and couldn't get it to fit - the filter box would not seal shut and the duct would not properly align with the throttle body. Sent it back to the aFe Power. Will I see similar problems with the VR-TCR-7 system?
Thanx.

Don, that space creates the cold air intake so that it pulls air from the crack in the hood. They put foam and a rubber seal around everything else so you suck in cold air and not hot underhood engine air.
