MAF vs ZO6 MAF
MAF vs ZO6 MAF What's the difference? Size? Connectors? Pics would help. Right now I'm running a standard ported F-body MAF. Inlet and exit size is 3 1/2". I looked at a SLP MAF yesterday and it was 4" inlet and 3 1/2" exit. 
i think i heard the zo6 maf has the air temp sensor buillt into it also which makes the electrical connection different. I have also seen adapters so this could be run with an f-body harness. I belieive this is done because of the increased size in diamter over the f-body
Thanks JimmyP, I noticed the Air temp sensor is intergrated in the housing, which accounts for the different wiring connector. I wonder if there is a size difference in the housing. Someones got to have pics out there.
Buddy,
The general concensus in the tuning forum is that the stock MAF is enough and there's little good that can come from switching to the bigger one. The MAF calibration is different enough between the two that it can make things go out of whack. I can probably find a few threads in the tuning section to support this if you want. I'll look later tonight.

I think they are 85mm which I believe is the same as the LQ9 used on the 6.0 H.O. motors. Are the connectors the same as the F-Bodies? I'm not sure. I'm just working off of some partial info someone prolly knows better.

The reason I want to change it is because when I dyno'ed it sounded like a vacuum sucking air through the filter. It sounded like a ton of resistance, even with a ported MAF. Maybe I should cut out the center bars.
How about the SLP Maf? Any comments on it.

im no expert but let me add my .02, jsut because the stock maf can support 600hp, doesn't mean that its not a decent restriction, especially on increased displacement engines

If you're going to do anything to the MAF, you really need to get the MAF table calibrated correctly. This includes porting, using aftermarket ends, or cutting out the bar. Many of the people in the tuning forum who are doing their own tuning have had issues that were ultimately traced back to the MAF. If I thought that the MAF was holding me back, I'd probably just remove it and tune the car speed density. However, on a stock motor I don't think it's going to be that much of a restriction. (Do you have an LS6 intake or still the LS1?)
Besides, I thought you were going to bolt on some belt driven device to cram the air into the intake... If that's the case, you're going to have more MAF issues once you start to build boost over a certain level.
if you mod your harness for the connectors.. or get a adapter harness.
and you use a OEM maf... as in 100% not modified, not tweaked, not "calibrated" but stock replacement MAF for a Z06 or a truck..
and you change the tables in the PCM to match the MAF (basically copy the Z06 tables or the truck tables)
then it works like stock.. but its bigger.
most specific questions about it can be answered with a search.
