Ok guys I'm kinda new to the world of jeeps but I'm looking to get some more power out of my renix 4.0. What are some parts. (Cheap bolt ons) I could get to build more power. I've already made a cold air ram air intake for it. And she's got after market exhaust. What else can I do!? It's got stock injectors I'm going to swap to quadrajets soon. What have you guys done to push more ponies? Thanks guys.
