My bad... I forgot to tell you what car I had. I have an 07 Silver WRX Wagon with a megan racing catless T/B, K&N drop in filter, boost guage, and strut/sway bars. No EM... I'm actually waiting for the AP but apparently they're on back order. And I have some Megan Racing headers, MR up pipe, and an A/F ratio guage sitting in my basement. I had a "show off valve" on for a week but after I was "enlightened" by NASIOC, I took it off due to it running rich between shifts.
