Let's face it: on the trails, a Rubicon usually isn't going to stay with a Vinson. Heck, I'm a Rubi owner and I know this for a fact. Is there anyway at all besides increasing displacement to give a Rubicon the Vinson's grunt on the trails? I've already installed the Warn 424 and from what I've read, I don't think a pipe/jet/filter combo will do it, unless those with experience disagree.

 

Is it not possible then?
