228HP/ 228TQ 2002 Auto with Headers.
Well I got my Cattman's headers installed and tune with the VAFCII. After I drove away I could tell the big difference.
My Maxima is runing 225HP/211TQ with:
Berk Intake, Cattman Headers, Cattman FastCat, Cattman Cattback.
I had my car Dyno last year in July, and made 202HP/200TQ with:
Injen Intake, Cattman Y-pipe, Cattman FastCat, Greddy Cattback.
I gain 23HP/ 11TQ with the Headers.
I never did a dyno run while stock, that was my mistake i should have done that first.
Here is my current dyno. I need to look for the A/F sheet. There was an accident inside my car last saturday night and had to take everything out and clean it. I will look for it when I get home from work today.
Here is my dyno from July.

I thought it would around 230 too, the dyno operator said it's probably doing 230-235 in other dynos.
Now that you mention it, I'm curious now. I will see this weekend If can go to a different shop and get different dyno reading. To see if it's still in the same range, I will definitely keep the A/F sheet this time, I have no idea where the other is.
But that extra gain I got from the headers is beautiful. When I'm in the tollway at night heading home with no traffic I go WOT and love it.

Well this morning, I went to Carboy Racing in Houston to have my car dyno on a DynoJet. My first pull was 219.9 HP / 220.3, Benny who is the dyno operator was able to tune it and after the 7th pull he manage to make 228.8 HP/ 228.6 TQ.
I did feel the difference after the tune, the car takes of faster now. He did tell me there seems to be a problem at 3.9 RPM he could notfigure it out since he did not have much time analyzing the problem. I just went for a dyno and ended up doing a quick tune.
Here is the dyno sheet, sorry it a bit small I will try to make it bigger later today. Also as for the run files, I brought my USB but they could not do it. Their system was in a odd place and the only way to save was in a floppy. I will swing by them again porbably monday or tuesday and get the run files.

You are making pretty good power up top
How the hell did it not downshift @ 3k in 3rd?

Many more, I got the spacer and BBK coming my way. Well the BBK may take a little longer. But my next major mod was either getting a VB mod with a TQ converter http://sgpracing-store.stores.yahoo....raupvabof.html or a whole new transmission http://sgpracing-store.stores.yahoo....praautrup.html.
I know in those links are for the 350 but when I talked to the owner he said they could do it for the max and the it would cost just be a bit less.

I know people change their MAF since the 2k2 goes out easily, thanks goodness mines still working perfectly. Also I read people change their MAF from 2K1. As fas a bigger housing, you talking about the AM600 MAF??

I see what your saying now. Now I'm guessing thats the Bosch 82mm MAF in your pic?

These things are $400 new from BMW but only $100 new from Range Rover. Your stock 5th gen MAF sensor will perfectly bolt right into the 82mm MAF with no problems.

It sure is. I've actually changed my set-up recently and hope to dyno sometime soon.
Seems as if you have everything in place (VAFCII for correction) so, it's all a matter of buying, installing, and tuning.

Could you please link me where can i get this maf? I tried google and bosch auto part site and can not find it.
I'm thinking of doing this this weekend coming up with my spacer and a re-ture. Well I'm hoping to get my car back from the dealership in time. I taking it back Monday morning to have the bumper re-painted since its starting to crack, even tho this was a brand new paint job.
Thanks,

His latest is an dynojet, where we can roughly compare between other cars on the site. Correction factor helps us level the playing field as much as we can, even though there is still a fudge factor between dynos. (
