Okay, i intalled my Uego in my car about 1 month ago with my Utec, and my Afr's were saying that i was hitting 12.5's on certain maps, well i just got a tune done with and LM-1 and from 3500 to 7500 my AFR's are 12.2 to 12.4 with no knock so what is the true number where we are safe? I thought it was mid 11's, should i try and and more fuel? car pulls nice right now

 

The stock maps from UTEC run very lean. I was getting 12's and the car would knock when I would hit boost. This is with 93 octane. I would add fuel until you reach at least 10.5-11.2.
