I have 01 trans am ws6. heads and cam longtube headders 42lb injectors.
I am swaping from the stock ls6 intake and tb to fast 92 intake and 92mm tb.
what mass airflow sensor should I use with the fast 92/92tb setup.
also what lid and coupler..

car dynode 405rwhp in current form clutch let go and couldent continue the tune how much more hp do you guys think I will gain with this new setuo.
thanks.

The stock MAF should be fine. Or a Delphi 85mm will work also

I ran the stock maf on my HCI LS1 setup, and it worked great...wasn't restrictive or anything

just thought I would have to upgrade maf. shocld I keep using the slp lid or go to 104mm lid.

First I'd ask your tuner what the MAP was reading at WOT, particularly above 4k rpm. I was at 451/415 or so, and at 4300rpm my kPa went to 96.

Ditched the stock MAF, went to a CLSD tune with a 4" piece of aluminum pipe from the SLP lid to the NW 92mm TB, and put down 460/420.

Pulls were done approx 15min apart.

Anyway, what all does your set-up consist of?

I am a believer in do it once and be done. 4" pipe, LS7 MAF and your set for whatever future mods you decide to toss in there

I would ditch the MAF all together and get a SD tune and a 4" piece of silicone tubing to connect the lid to the TB.

my setup consist of
eps 226 234 cam
ls7 lifters
tfs 215 cyl heads
arh 1\78 longtube headders with y pipe and cats
42lb injectors
ls6 intake
stock tb
slp lid and stock maf

going to be adding
fast 92mm intake
nw 92mm tb
slp underdrive pully

I was told by tuner to get ls6 maf.

should I get a bigger lid and maf or just go the ls6 maf route.
will bigger maf make more power?

The dr there has your answer. You need a scan of the engine now at WOT. If you see anything less than atmospheric pressure when you do, you'll see gains from an increase in size. If you see less, your dealing with restriction robbing you of potential HP and TQ.
