so. I have an APEXi AFC Neo and an AEM UEGO wideband O2 both on their way. should have them by the weekend (hopefully) or early next week. I'm going to be using them for once I have a turbo, but I was hoping to squeeze a little more power out of my car in the meantime. I'm a total newb to tuning though. I figure that what I want to do is just add/subtract fuel as necessary to maintain a steady air/fuel ratio. But what ratio should I aim for? also, what should I do with my timing. I'm currently advanced to 18 degrees, should I just set it back to 10? any advice and tips would be useful.

14.7 is ideal for emissions... not power

That's probably too rich... The best way is to get on a Dyno... cause engines are all pretty different depending on condition and stuff... -------------------- "It's ok to be naked girl...
