    Hi Guys, I am sort of new to the forum, and have a couple things I still have questions on. I bought my WRX about 2 months ago, and really want to get started voiding my warranty. But first, I wanted to make sure I understood everything correctly. I am planning to make this a serious project...
  2. lighter pulley, worth it? boost creep cure?

    Dealership, Vendor, and Installer Review
    I was thinking about buying a lighter pulley, what can i expect from it besides faster revs? Also if i have a catless 3in. TBE would a pro-tune counter-act boost creep, or is it eminent that i buy an EWG?
