i have a custom dynoflash,intake ,exhaust ,mbc,ported and coated stock exhaust mani,hks 280 exhaust cam, head studs, buschur ic, licp and safac2 my wide band read 11.5-11.7 at wot all the way to red line.if i put c 16 can i lean out some more? any input is welcome.thanks

 

wow on a dynoflash all ran you at 11.5-11.7? i didn't know he went that lean

 

You need a datalogger to see what your timing is at and to see if you are knocking before you even start leaning it out.

 

12afr is fine on c-16 but watch your knock count

 

+1. When I tune my car on c12 I shoot for high 11s to 12.0

 

after a dynoflash tuning it was at 10.00 but i lean out to 11.5 on top of a tune, my car it's been runing good like this for over a year .

 

i being runing 23psi on this set up with no problems at all. i like to boost it up to 28 psi at the track with c 16 and lean it out a bit more ,i just want to know if it's possible without blowing out something

 

I've ran it to about 12.0-12.5 on C16...ran the best at that AFR. C16 is pretty knock resistant as well, especially at 5500+ rpms.

 

careful with the afrs on C16. Try to stay in the mid 11's at a max lean.....
