P&P MAF, wow!
I hesitated for a long time to mess with my MAF. Never even wanted to take it apart. I finally looked into it and found that practically no one has had trouble from removing the screen.
Well I took it a step farther and did a port and polish similar to the way I did the TB. The lips left from the screen where terrible and there was allot of extra thick material on the front half, much like the TB.
I am quite amazed by the improvement this made. The throttle response increase was about equal to the the TB porting increase. Also I was getting better fuel economy on my drive to class just now. Power seems closer at hand and the intake makes more of a gulping noise like what you get form a short ram intake when you stomp on it.
I am not the type to spend money on things like MAF's and TB's when I can do them myself. Time well spent for as good or better of a unit than I could have bought.

I have a scan tool and observed the live data. Its not a big enough change to where the computer cannot adjust for it.
It had a pending code for to rich on bank 2 at first, but I did not have to clear it. It worked itself out and now there are no codes or even pending codes. It worked it out after a half hour drive.
Im not suggesting that people who do not know how to carefully handle a MAF, and where exactly to port on it should go do this. But if you know what you are doing, it does make a difference.
I was interested in doing this because it was the last part of my intake tract that could use work. I have a K&N intake, p&p TB, and an LS6 intake. So I may have benefited more than a stock car would because it was the only restriction left in the intake plumbing.

If you want a quick 3 tenths and 2 MPH drop the K&N for a Vararam.
I didn't believe it until I tried it. ( Verified with 100's of prior runs)

Hmm, I am very skeptical of the ram-air thing. But I do believe first hand experience. I contemplated the VR when I was ditching the crappy SLP "filter" (That was not even an intake.) I chose the K&N because of the CARB EO number. It has been my goal to modify in ways compliant to ****-fornia.
So far everything it compliant. The gears and TC, the Cam and Heads I am soon to install. The K&N, LS6 intake, P&P stock TB and MAF, x-pipe/catback; Everything is either legal, or undetectable and will pass visual and the sniffer.
What filter did you go to the VR from? If you picked up 3 tenths after switching from a K&N, that is very good. But if you went from a stock ait-box, than its a no brainer!

I had a clear increase going to the K&N from the Blackwing. Im sure the VR is a bit more, but the K&N is a great unit and totally legal. Comes with the air-bridge and deletes the baffles at no extra cost too. If I tracked the car allot, I would defiantly consider using the VR.

My car had a VR when I bought it. so I can't speak to the improvement.
I have logged my car on every 1/4 mile run. as well as a lot of street driving.
The VR does allow the IAT to run at ambient.

Well through a full range of rpms and testing, it has no issues, so I think the computer figured it out fine.

Just curious if you had a quality power duct and smooth bore coupler installed with the Blackwing before switching to the K&N setup? Thanks...

You will most likely feel a FULL THROTTLE power increase BUT,, you will suffer in part throttle *fuel economy* and your PE (Power enrichment ) will be RICH sacrificing power at top end. A quality professional TUNE will fix that!!

I believe you, but I have heard of more than one engine becoming hydrolocked in heavy rains with the Vararam. The young guy on here that just sold his A&A kit told me he lost his engine b/c of a vararam. He hit a large puddle of water and BAM - lost the engine.

LOL!! 
If you do STUPID SUBMARINE stunts with a VARARAM installed,,,,,,,,,,,,, YEP,,,,,,,,, you will hydrolock the engine,
If you do STUPID stunts in water with an OEM set up,, its possible to hydro lock the engine!

Interesting... I have been monitoring my live data and see no noticeable changes in rich or lean signals. All I have had happen is an increase in response, slight power possibly, and better fuel economy all around. Any changes seem to have been for the better. The car is tuned, and will be tuned again soon after I finally put my 243 heads on and cam it. Maybe I got lucky, but I must get lucky allot because from past experience with many vehicles before this, I knew it wasn't going to be a big deal.

you're not getting lucky, you're running in CL and the 02's are correcting for it.
If you don't have a wideband and software like HPTuners, you're not going to see what's going on with your fuel trims. There is no way that you can pull off the maf screen and not need to tune it to get the fuel trims back close to 0%.

Also, how do you figure the car is stuck in closed loop?
