AFPR Adjusting
Alright, when I install this afpr, should I screw that **** in half way and then adjust it like that? And which way do I turn it to decrease pressure and increase pressure? Thanks.

Alright thanks for the hint. My mods are listed on my page. I recently had the ultimate TBI mods done and added an injector spacer by Joe (Camaroracer1992@yahoo.com) He did a great job. :hail: :hail: :hail:
