AFR & Boost
AFR & Boost What should I target my AFR for? I've heard 11.5 is best and I have it hitting 11.5 perfectly right now.
Also, what kind of AFRs should I be seeing at low rpm with no boost/load (cruise), I've seen some tunes that have it running at 14.0:1.

I shoot for 14.7 at cruise. WOT depends on a lot of things. Amount of boost, timing, load.......Really low amounts of boost I usually shoot for the low 12 range. Big boost and pushing parts to the limit I will go richer like 11:1. Usually though I will shout for around 11.5:1 at torque peak then taper off to 11.9:1 or so at the shift point.
since i'm on a stock motor i target 11.0:1, gives lots of room for error with no real power sacrafice. On the dyno my 11.0 tune registered 10.5, I leaned it back out to 11.1 and only gained 10 rwhp.
Main reason i run it rich is #7 seems to go first, my guess is it's because of a lean condition. So I run it rich.
