Hey warren s, how in hell did you get the MAF to mount at the throttle body? Mine just had to go at the other end of the power duct.
Yes I'm getting a CEL, but for $20, a friend will add fuel to eliminate the lean situation.

One thing to note is that you can definitely tell there's a lot of turbulence going on because when you keep the same speed going down hill or coast for a few seconds, it hesitates or surges every now and then. I'm sure that it's because there is air getting in that isn't getting metered by the MAF.
Aside from that, it's the greatest addition to the car so far.

Threw lean codes right away, but that happens almost every time with de-screened MAFs. Aside from that, it made an enormous difference. I didn't get to run my car at the track before the vararam was installed, so I can't give you numbers, but you feel the difference from 3000RPM and up. Before on the freeway if I was in 3rd and punched it, it wouldn't light up the tires. But now it does.

I agree the VR was somewhat of a nuisance to install. Tight fit for sure. Had to bend in the radiator shroud a little. Silicon joints only bent so far. Mine threw codes after a couple days worth of driving, turns out the MAF had oil on it from the air filter. I used some MAF spray from NAPA and it was fine there after.

i was being slightly sarcastic. The act of removing the bridge and maf isnt hard, but if your varram is like mine, putting it back together will be hard.
Im going to see if 1 of the mafs that i have laying arround (from other manufactures) has a honeycomb that I can use. well for testing to see if it helps on my car, if we ever thaw out that is.

I used the coupler that came with the power duct. had to cut a small square shaped piece out and a very very small bit of WD-40. Slid right on.

My VR install took about 2 1/2 hrs with the wifey helping me with the usual "hold this" and "hand me that" .
The PD take about 15 min tops...worth the money IMO. The additional thing I did was to get one of the Halltech honeycomb MAF screens,since my 02Z did not have one.
These 3 items renders a good SOP diff.How much I do not know.
