Too much of a good thing?

are any of you monitoring your air/fuel.... with all this boost etc I'm wondering how many are running lean.....

"too lean = car runs great right until it blows up"

leaning out the MCS engine can get you 10 whp (or more) just wondering what a/f you are all running as I make some decisions...

In fact, I was worried about just that recently when I took my car in to the local Unichip tuner. It was just to have Dan dyno it so we could look at it to know if I was safe in the much cooler weather (originally tuned on a series of 100-102 degree days).

Car was running really strong. Turns out the afrs were in the 13.5 range!

We reset them to the 12.0 region and I lost about 10-12 whp...

Got about half back with advancing the timing.

Oh well, at least for me, better safe than sorry!
