streetported, full RB exhaust DYNO day comming...

i have a S5 NA streetported with a RB full exhaust.
i was wondering what my a/f ratios woudl be aroudn right now. i am about to install a S-AFC on the car to see if i need to adjust the fuel when i dyno to try to get some more power atteh wheels. i have been driving the car around and power doesnt seem to fall off all the way up to the fuel cut 8600rpm? on the tach however accurate that is.

so my quastion is what do i tune the AFR to on this car, considering i will keep teh stock timign and will want to kepp running the 87 octane gas.

any other suggestions woudl eb great.

perfect would be 14.3

but anything around 13.5 to 14.0 would be ideal for an NA

and then u can tweak the timming as well...becareful though.

i wanna tune for power and reliablility i dont want the motor to pop. i dont wanna cahnge teh timign since i am already gonna run 87 octane and dont paln on goign any higher. i was thinking of tunniing to 13.5 from 5-8.5k rpm, 13.8 from 3.2-5k rpm and 14.1 under.

any one advising against thins pelase speak up
once again the motor is street ported, full exhaust, intake and pineapple 6 port sleeves

Well here is the info I have, don't know if its accurate or not. Tune to 12.5-12.8 for NA's, and place the ignition pickup on the Trailing #1 cable.

Hope this helps!
