The weather in Florida has been unseasonably warm but we have had a couple of colder days here and there. We finally have a day in the high 40's today and I am seeing AFRs at around 11.9. My mods are Cobb TBE, 3-port, Intake, AGP 3.5" intercooler and UICP, and I am running the Cobb Stage 3 OTS map.

Is 11.9 dangerous? Normally I am sitting at ~11.5 with ambient temps at 60 or higher.

 

My car is at 11.8-12.5 @ WOT and it fluctuates rapidly. It's funny because I get no knock at all...I don't know if I should be worried or not.

 

lol my temps are below 0 and my Afr is between 10.2-10.9. get your etune already Mrak

 

My afr's fluctuate between 11.3-12.1 on Cobb's V403 stage 2 map... Knock counts are virtually 0. Might see 1-2 counts occasionally.. Very infrequent though.
