That's a very good #. That's about about what I was running in my 03. What mods do you have?

You shouldn't go any bigger than 660cc w/ a AFC and no flash. The AFC tricks the mass air sensor to make it think there is less air going through it than there acually is. If take to far in the negatives, (past -20%) the mass air thinks there is no air going through the Mass and advances the timing and causing detonation. That will wreck your motor in no time.

Turbo XS is a good core. I have it and it's huge.

As an update, I noticed that my karman was much lower after the silencer, like in the low 1500s. I was kind of bummed, then I also noticed my boost had dropped a few psi.

I cranked up the boost a little, and now I'm reading in the low 1600s again and car feels stronger. I need to find a way to quiet this thing down without killing too much flow.
