ls7 credit card style maf to ls1/lm7

[beingblueeyes]

I see its been done on ls1tech but has anyone went to a ls7 maf here?

theres no benefit to doing that mod. its a nice cost for no gain

i know your deff correct on a 5.3 but what about 400ci+? it seems like a lot of 400's are running SD tunes due to the huge amounts of air needed to feed them and the intake restriction a 5.3/5.7/6.0 maf causes.

when its time to upgrade its time to go SD on the gmt800 trucks. no reason to buy that maf

What about upgrading to a aftermarket maf like I've heard of but never seen a 100mm Lingenfelter maf or similar equivalent?

(on my ls2 gto) im running a 102 throttle body, 102 intake, and ls7 blade style maf fabbed into a australian over the radiator intake. I havent been to the dyno yet, but a friends car picked up 20whp with this intake and switching the maf's. Perhaps its got something to do with the huge cam im running or the combo of parts, but the price i paid for the maf as compared to one of those overpriced 92mm or 100mm maf housings is insane.

I really dont know about how much air you would need to move on a 5.3 though, i mean i am a 364 with literally every single bolt on made for the ls2 aside from power adders..well when the ARM switch is off ..

i had no idea there were serious changes. oops haha..

if you had a LS1 gto then the pcm is same as these trucks, a LS2 gto is a newer pcm
