I finally put my uego in and i'm getting 13.3 a/f while in boost on a 9.5psi s/c. Anyway else want to chime in? Seems a little lean to me ?

 

Has your car been tuned yet??

if it has then i dunno...

 

OK.. Thats very bad..

 

thats not running lean. lean would be any thing higher then 14.7 and any thing lower is running on the rich side. stock trd setup at wot i bleave is 12.5 on the rich side.stoch is 14.7 and when tunned for max power you tune from 12.5-13.3

last time i check.. under boost 13.3 is lean.. I tune my car at 11.2 under boost

 

13.3 is fine as long as the ignition tune is compensated and not tuned aggressive, afr tune is half the equation

 

when i was s/ced with that pully and intake + headers I would see 12.1 afr

 

is that on the s/c reflash? it maybe something to look at since i believe the ignition tune is like standard but the afr is lean..

 

yea its trd tune, its pulling a crap load of timing.
