Dyno Day on Saturday - RESULTS INSIDE
So I have a 9am appt with Keith at AZDynoChip on Saturday to get some baseline (well not exactly baseline anymore) runs in to see what kind of numbers I am putting down with the intake, tune, and pulleys. I am really looking to also make sure that my A/F numbers are good.
So I am wondering what type of range am I looking for. I know that optimal (from what I have read) is between 12.5 and 13.3. But what is a safe range? And other than some hp loss is it okay to run a little on the richer side? I know that lean can be really bad, but a little rich is okay right?

Be sure to tell keith that the guy with the blue Whippled Roush says "hi". Keith will explain all of your questions when you get there, he is probably the most knowledgeable person I have yet to meet when it comes to tuning cars.

Is your car stock???? If so that's pretty damn good.
 Your A/F looks dead on balls accurate I would say. Dips down and gets fatter under WOT, looks just like it should.

No, it's not stock...
C&L Intake with C&L's 91 octane tune from a Predator Steeda UDPs.... that's it....

Those are good numbers for non S/C. Like Mark said, the dip in A/F is in the sweet spot. With exception to idle, my A/F is between 11.5 and 11.90 across the board. I could gain a few more easy ponies with a more agressive tune, but, I like running a little rich and I still get up to 22mpg hwy. There is no "safe" tune
