if you haven't been around, i'm as close to that as it gets.

i used to run with a restrictor plate that was 2.5"x2.5" square. any larger and it won't work. fuel mods are necessary. i now use the 3G eclipse MAS. it's smaller than the modified MAS, but i'd rather run something unmodified. it's still larger than the stock MAS tho. depending on mods later down the road, i'll probably upgrade to an evo 8 MAS.

 

Piggyback ecu or reflash assumed that you are running a normal MAF, not a hacked one. Thereby, their upgraded perimeters won't work, usually for basic mods.

Besides, both system bypasses the AFC.

Rhyzin,
You mean the 339 MAF (hopefully got that number right). That would be interesting.

 

there really is no need to go to the 399, but would be one of my last NA mods. a precursor to turbo

 

The slightest changes in that bezel make HUGE A/F changes. Hell even moving that screw out which is about 3/8" wide by a 1/4" tall makes big differences in your mixture.
