Not that it matters, but I think that the LS1 MAF casting isn’t that rough to start with, and I’m not sure any gain would be worth the effort. Arguably, the screen in the MAF gives more resistance than the as-cast sides. Of course, if having an as-cast MAF is a real concern, you could, for the same price, get a tune and go strictly speed-density and ax the MAF entirely. ---

huh? i want it polished for the GN, i already got rid of the stock GM MAF and replaced with a better flowing ls1 maf, i just want it polished. It flows fine… im not polishing the inside. same price as what? the mafless system for a GN is more than the 70 bucks i payed for this maf. Original Mafs for the GN are very hard to come by, all of the aftermarket are junk jap shit that might last a year. ---

And if the MAF is a different size than the original GN one, doesn’t that mean you need a new resistor or tune to accomodate the new values from the MAF? In any case, I figure any machine shop can do that, or absent that, find a buddy who doesn’t mind sitting with a Dremel. ---

GN is 3 the ls1 is 3.5, i use something called a translator, the old GN mafs wouldn’t hit 255 grams at a steady pace, the numbers kept dropping off, so the ls1 maf keeps them steady. plus the car idles alot better. ---
