this has been a good thread for me because I've been struggling to believe intakes do much on these cars.
I am suspecting that when people see gains with just the intake and no tuning that it's the relocation of the sensor tricking the ECU and that you could get the same results as part of a tune and just leaving it in the OEM location. If I'm right, this explains the "gains" the all the manufacturers claim and why it's a slight of hand.
I think the real test of my theory would be to tune a stock car on a dyno and run it. Then revert the ECU back to stock, install an intake run it for numbers again. Then tune it with the intake and run it again. Compare ALL the pulls and see what happened. The tuner would need to be honest enough not to manipulate the tunes to show results he wants.
thoughts?

At the dragstrip, the car moves through the air at a changing rate and the location of the inlet makes a difference whether it's in an area of increasing, decreasing, or static pressure and temperatures.

PS: My bolt-on trap speed at 125 MPH "really" KICKS BUTT!!. Oh, and I think second place in bolt-on GS is running a Vararam and a custom dyno tune. Check it "all" out.

it's all very debatable since adding ducting to a filter in a stock location is not a CAI either. physically moving the filter to a fender or some other location would be a real CAI.
the stock design is good and does have some ducting to it, plus when you're moving all the heat is back on the firewall
this is why I would like to see a test like the one I proposed done, we can answer this with science.

C.....cold
A.....air
I......intake
air brought in from outside the engine bay is considered to be Cold Air.
This is a simple principal and really not that hard to understand, no matter which devise you use to accomplish it.

The VARARAM is the BEST, has always been...and will always be.....
From a tuners standpoint, it offers the cleanest maf signal...most horsepower, and the the guys that
run the company are THE BEST!
Here at Corvettes of Westchester we have never, and will never sell anything other than the VARARAM!
Read your install instructions carefully.... Measure twice....cut once....and be sure to READ and understand the instructions BEFORE you get started.
With a VARARAM, you can't go wrong.
Most other intakes we have tuned case airflow "anomalies" which cause idle and decel problems and while they install
easier it's just NOT worth it.
YOU WILL NOT MAKE AN MORE POWER WITH ANY OTHER INTAKE....PERIOD.
