The difference is instant boost, I guess it's the overall added volume?! We will find out on Sunday as I have not even been 2 miles with them yet, I'll report back
Just out of curiosity, did you tap your boost gauge into the open "tank" on your stock pieces, or tap into the inlet tubes before the tank? The main restriction of the stock units is just before the tank so the readings will be understandably different if you were tapped into the tank portion.
Definitely let us know how well these things work. I am guessing they will be great!
