Rich or Lean So I recently installed a TSP 233/239 cam and Pacesetter LTs and ORY untuned. My question being, is my car running rich or lean? It smells like fuel so I am assuming it is running rich.

A more broad question is does a car usually go lean or rich after mods like LTs and a bigger cam?
This is in this section because I am currently untuned and am wondering how bad it is to drive (tamely) without a tune.

Well, to be more specific, you'll be significantly rich in and around idle. Above that, you'll be significantly lean and running less than optimal timing. The fuel trims will be able to compensate some. But, most likely not enough.
