Under boost my tuner said .87 is "big power." Doesn't this equate to a 12.87 a/f? Seems a bit lean to me. Is this okay for E85? Right now I'm tuned at .86. On another thread someone said, ".805 full boost so im happy..."

Thoughts?

Is .85-.9 for idle ideal, how about during cruise for max milage?

Thanks in advance

 

might try the tuning section for this type of question since it directly tuner related

 

Good call. I forgot about that section since I spend all my time here. Not sure how to move a thread... Maybe the mods can help?
