I like this mod, if it proves to gain at least 10 hp. Especially if its a mid-range gain. The other big plus, over other mods is that it doesn't require a tune and is easy to install. But I would like to see some independant testing, as i'm sure alot of others would as well.
I would like to see this tested on a bone-stock gt. Back to back dynos. W/o an intake or tune or boss mani, for a baseline test. Then add the mods and tunes and see if the gains, if any , hold or get better. Then f/i and test.
