several reasons.

i had the 90mm MAF for a while on a N/A 3L with an ATX, then on the same motor with a MTX. i purchased it then because i had F/I in my future and wanted to be prepared. overkill for a N/A 3L, yes. ill even admit my intake plumbing looked like @ss and was all ghetto-rigged like a 16 yr old ricer would do. i drove a good 10-12K using that MAF, and had ZERO stalling or idle issues. not a single one!

now as for the setup im planning. the maf will be connected directly to the air filter, and be located in the fenderwell to draw in fresh cool air. it will then be plumbed to the inlet of the turbo where it will then go through a water-air intercooler before entering the engine. the lightning MAF should work beautifully with the setup im planning, look good and work flawlessly. i will be pushing 10-12 PSI on an oval port 3L and should be making decent numbers. and i will still have a little more headroom if i want to make a bit more power.
