From what I see from most tuners on pump gas it seems around 11.5 is good for power and safety. I guess I am hoping that some of the tuners on here could let me know thier insight on all the AFR's from Pump (93), 110 R/M2 and C-16. I believe most DSM's are happy around 12.5 or so on C-16 but I may be wrong. Please let me know guys, thanks.

 

No tuners around these days?

 

I tune my afr to start at 12.0 (While low fuel pressure relay is on) on low boost then taper down so I get a good quick spool up. I am usually running atleast 11.5 by full spool then taper down to 11.0 by redline. At peak torque around 5k your afrs will want to creap up but be sure to be 11.5 or lower at this rpm to be safe without worry. This seems to work best for me for power and knock on 93 pump fuel.

On Race fuel 12.5 to 12.0 works the best to run the maximum ign timing.

This is just what works for me so good luck tuning.

 

Thanks man! Thats kinda what I figured and got my pump gas pretty much nuts on. I havent done race gas yet but I need to redo all of it this weekend. I am gonna try to tune the car to run decent with 780's with an AFC. After the turbo hits it will be easy to tune but before that... I hope it runs well
