I think lean is mean. I tune for 11.7 or so +/-...doesnt seem that 11.9 has hurt me yet either.

Also depends on what fuel...Pump, Pump/meth, E85, E98, C16 (any racegas really), diesel...okay not really on the diesel.

12.50-12.0 during spool, 11.7@pk boost, tapering to 11.1 by redline, pretty much 11.3 average. This is on AZ 91 pisstane. On 100 octane for drags 11.9-12.0 average.

I usually do the same. Its richer than I prefer for my OWN tune when its dialed in, but it leaves some room for inconsistencies in gas quality from station to station for a good,safe tune. It also helps keep things safe thru climate changes.

Na its more like both my cars run MUCH better with the proper AFR and have MUCH less ignition issues all the while being easier to tune and more consistent from day to day.
