i think 14.7 is the optimum if im not mistaken?

 

i think 14.7 is the optimum if im not mistaken?
or i think that is what stiochmericc (sp) is either that or that is running fairly rich
or i dont know what im talking about
im realy going to learn something from this post

 

11.4-12.2 is good under boost. I tune for 12-12.5 in boost on the street, high 11s on the dyno.

 

but i should always run a little rich which whould be around 12.5 under boost?

 

10.8 would be RICH, 11.4 is conservative, 11.8-12.4 is very nice for a street boosted car, anything over 13.0 @ boost is RISKY, you might detonate. I always tune for 12.2 flat AFR's on cars running more than 10PSI. 14.7is STOCH, Idle and crusing. mild acceleration 13.8 and so on down the road. read some moates.net DIY tuning ***** they full of KNOWLEDGE

 

thank you for the helpful advice
