Ive been pondering the information I once read about airfuel at 13.9 being just right for economy and performance. Any one have a similar build to mine running afr at or above 13.9.? What are your thoughts on that. I have run 13.5 with my build and it just smelled too gassy and I worry about wash ing out the cyclinders with to rich a afr.

I will be getting the TTS tuner and dyno soon and want recomendations afr for my build. Thanks ahead of time.

where are you talking about? WOT? If so that is a little to lean for performance. 12.2 13.6 at WOT just depends on if it needs or wants it.
cruise 14.0 14.2 .for a little better mileage at light cruise.
setting the afr to 13.9 across the board ,or any AFR across the board,is not taking advantage of a very tune-able delphi system.
cruise 13.9 on a pretty hot compression motor would not be out of the question. and would not wash down the cly though.
as load increases say 80 kpa 40 - 60 % throttle 3500 rpms 13.4 -13-6
