Would having an 80mm LMAF be better than having the stock GT MAF?
I'm only running PI Heads, Comp XE 270's, full bolt ons, and 24# injectors?

And is there any real difference in the 80 LMAF over the 90, besides the obvious size?

 

no a larger MAF isnt necessary unless your F/I

 

i thought the stock maf was an 80mm

 

Yep!! Leave it stock

 

Stock MAF is already 80mm. You wouldnt gain anything by using the "Lightning 80mm" MAF. Basically the same thing. Even when supercharged you would need the 90mm.
