What is the optimum air/fuel ratio and timing to get the most out of these trucks without burning something up while using 93 octane?? I am curious to see what you guys feel the limit is.

Thanks

 

14.7 is the stoichiometic best air/fuel. It will of course blow up your engine.

Good question. dont know about timing but at WFC on saturday, on side 2 of my flip chip my truck ran lean in 3 gear on 93 octane. Found & talked to Jim from JDM about it and he said the air was to good for side 2 and to change over to side 1(street). He said he was commanding a 11.7 to 11.9 to 1 fuel ratio on side 2. Switched over to side 1 and truck ran great, also ran over 2 MPH faster. dont know what the fuel ratio is on side 1.
Bottom line, in GREAT air with 6#'s extra boost 11.7 to 11.9 is not enough fuel. Hope this helps.

 

No slam on our(me too) guys but I think this is a tuner question--and I bet each one will have a different answer/recommendation.
