I have read some past posts about how some mods will lean out the car and others will make it rich. I understand that I will not fully know what my AF ratio is until I get it on the dyno but the only dyno I know of around here is in Las Vegas and that is over a 6 hour drive from here. This is a list of the mods I have so far, best educated guess on whether I am running a little rich, a little lean, or right in the middle.

BBK LT's. BBK catted H, Dynomax SuperTurbo 2.5" cat back, Densecharger CAI, Accufab 70 mm TB, C&L plenum, March UD pullies, and a Hypertech. (some other things that dont affect the engine)

I know that the Hypertech plays with my timing but couldnt get a number as to how much from their tech guys. I have heard that LT's make the car run a little rich, dont know why, but that is what I have heard. So, how badly do I need to make a trip to sin city? Or am I within a "good" curve? Also, I bought a set of PI heads off of ebay to get them P+P'ed and cammed. I know that this will totally screw up the AF curve but I will deal with that when the time comes. Thanks for any help I can get.

I'd guess you're around a safe 12.7...a little on the rich side...but safe...

I think with all the intake work, plus the LT's you went from lean to rich to safe.
