02 Dumps ?
People are reading to much into this. The ghetto ebay 02 housing showed 15WHP on Buschur's dyno on his own race car, he now sells them. The Evo Power Mods 02 housing owns even more as it has the largest internal area and flows the most which is what you want. EPM is what I run it is what I recommend.
No offense, but I'm going to have to disagree here. Please help me understand how "the largest internal area" is a benefit? Did you see the huge obstruction that I posted on the previous page? The EPM unit goes from 2.5" at the turbine outlet, to a 3" section of tubing, and back down to 2.5" at the flange (also known as a bottleneck) without even attempting to make a smooth transition. That wall of material is going to cause turbulence and hinder flow... Not to mention the mild steel flanges that rust and the lower intercooler pipe fitment issues. Does it do the job? Yes. Can it be done better? That's why we made ours 

Decided
Well. i made my choice. I'm going to give he map unit a shot. thank you chris for the impute and your time sir. hope this works as I'm expecting

Dumps seems like this is the single most debated thing in all of the car world haha. Youve got dump vs regular o2. then youve got dump vs dump...2.5" to 3" back to 2.5"...3" all the way...2.5" only, ebay housing ftw, screw the donut gasket, eat the donut gasket. Im making an o2 housing out of legos, screw this.

its funny because thats what Im likely going with to try is the MAP. Im going with an fp black setup and I do plan on getting both a ported/coated megan AND a dump and swapping them out between dyno pulls to see if there are any huge differences. From what it sounds like the dump is 100% necessary on the black and there will absolutely be gains to be had from a dump, but this is something I need to see it for myself in front of my own eyes.
