Tial, baby! So far, it holds 26psi perfectly, and it's loud enough to make me embarrased sometimes
This is my second one, my old one was red. My 2G came with a Type-S and I hated it. It made this loud whisteling noise that I thought was completely rediculous, like it was trying to be louder than it was. I took it off 3 days after I bought the car & installed this Tial.
