Actually, the 2000 Pontiac GTP Ram Air, while QUICK isn't overtly fast, and since the ram-air induction - much like this case - in actually forcing more air, as it should be, any engine will lean out if the TPS and MAF are talking to the ECU accordingly, only so much metered air will be registered, at any given point.
While I always like a great equation, other particulars should be taken into account, for said variables: Diameter:Flowrate (psi) from point 'x' to 'y' on the throttle, no RA effect, on the MAF (we'll say not moving, on a dyno) in comparison to the same control parameters on the highway...
NTM a direct scoop installed, instead of 5' of erroneous piping to slow down/ inhibit the air flow to the intake.
On the highway, you can DEFINITELY feel when it's leaning out (also illustrated on ****-retentive datalogging), where the standard power lacks, vs. where the RA induction overshoots the mark of the MAF's metering parameters.
I think as long as the appropriate flowrate is available, going back to the topic, at hand, your MAF won't dip, too heavily; though it will show leaning out at a progressive rate, under acceleration.
Secondarily, we weren't talking about an increase in power, but an increase in air-flow. Proven by his need to now bump the AFR, to rich, via the Emanage. If this weren't having any effect upon his AFR, he wouldn't now need to adjust it.

My avatar is not of my car but a generic one I found somewere 
My Vert has the headlight lid scoop which I think is pretty ugly but it may have some kind of functionality now that some cooler air is being drawn by the front-top directed hose of the trash-CAI... I never thought of this project as a RAM air intake, specially when most Costa Rican "high ways" don't allow more than 80kph (50mph)
I'm already thinking of my Trash-CAI v2.0 so be prepared!
Regards.
PD: Experts, remember for the total intake area I should be looking for!

are you freaking serious? this is horrible lol
you just defeated the purpose of in intake.
go back to stock air box lol
Later down the road you will realize how silly this is and will eventually take it off.
Im not being a hater, I just don't see this being beneficial.
That original filter with the shield was fine.

Cerm, if you get the chance, post your AFR readings before and after using your invention...
I'm curious to see where it's leaning out (RPM, speed, etc.)
I got to wondering something and want to look at the data-log file, from the eManage, just to verify.
Trash.0 (That's what I've been calling that fucktard on TV...) FTW.

Lord knows I'm a fan of homebrew solutions and can applaud the creativity employed here but the base approach seems flawed to me.
The problem:
-Airbox has been removed and a cone filter installed in it's stead.
-Cone filter only has access to pre-heated radiator waste air.
Your assumption:
-Fresh, ambient air must be directed to the filter.
Your solution:
-Build an Ikea version of the stock airbox, feed it fresh air via ducts.
In essence, from the very beginning you assumed "Must create airbox" and went from there. This lead to a shinier version of the stock arrangement- same location, identical function, worse fit.
If you look at the space in the front of the radiator- especially if you have no AC- you'll realize that there is a relatively large area that's not exposed to the elements directly and is full of nothing but ambient air.
Instead of bringing air to the filter, you're can bring the filter to the air and simplify the solution considerably.
You no longer need to build any sort of enclosure- you've just repurposed the nose of the car as the "airbox"- and only need to connect the filter to the MAF (which only requires tubing).
The filter is now living la vida loca- sucking in all the best quality air available (without you having to wonder if it's constrained by your enclosure)- and the engine bay has been decluttered and simplified as well.
I used this very approach on both my 7's, the rotary FC:
And the mongrel FD:
Both cars are daily driven and have experienced monsoon-level downpours with no ill effects.
It's a viable alternative you might consider.

Have no way to see the effect on AFRs.

I LOVE IT! i made mine from cheappy baking sheets, car weatherstripping, hardware, and spray paint. ive drove the car very very little before and after the CAI, it does sounds better and improve throttle response though.

Perhaps you've confused "opinionated" with "knowledgeable".
However, forging on...
Your setup fails my requirements by functionally duplicating the pre-existing stock airbox (to the point of retaining the stock snorkel, even).
It does appear to have been thoughtfully designed and constructed and I'm sure it works fine, it simply doesn't meet my (self-imposed and completely arbitrary) criteria though.

Everything is true!
I agree with all opinions written lately!
1. My car didn't have the original air box, in fact I looked for the stock box because I wanted it back... to no avail (I didn't looked at this forum though)
2. I have all commodities (AC, Windshield washer) that obstruct the filter relocation to the exterior and I don't want to remove them (yet) so moving the filter " to the outside" was not an option (yet)
3. I'm little crazy and love to make things with my own hands even if not of real benefit or use
4. Other air filter enclosures I've seen are of the "squarely" design and I though "why not to change shape?"
It's true that the best to get fresh air with no restrictions and not "duplicating" the original air box is to put the filter outside!
Somewhere in the future!
Regards!

Had you looked in this forum you'd be buried in airboxes...hell, I have two you could've had for the cost of shipping.
It'd be interesting for you to swap between the stock box and your homemade version...see if you noticed any difference at all.
The OEM part is probably quieter and I'd guess any "performance" advantages- either way- would be more imaginary than anything else.

Clokker bad thing is that I don't have the stock box... removed by some P.O.
And yes, usually "***-o-mometer" is very subjective and influenced by imagination
Regards!
