That might be a wiring issue then. My stumble didnt come on until I installed 750s and a return.

How does the SAFC (or AFC-neo) handle the air/fuel ratio when boosting less than what it would be at wot ?

I have only got to maybe 5-7psi and the safc did not change. It stayed around 14.7ish.

i have all my low setting at -15 it works for me great 14.7ish throughout the powerband besides a stumble at 1950rpms because i have a return line kit.

i have a problem of my own my rpms read exact and throttle looks alright when i give it a lil bit of gas but when i am at full throttle it only reads 90% the most could this be a bad throttle body position sensor or what could the problem be i would appreciate the help

Well, if you wired the TPS wire to the map wire then that could have something to do with it.

okay here's my problem, so i hooked up the safc and it powers up, but the sensors don't read anything, when i change the fuel maps it has no effect on the motor, and when i turn off the car and start it back up it does not keep the settings from before i turned it off. i have checked all of the connections and they all look good. also how far should the gray wire be connected away from the white wire, if that has anything to do with my problem? and i want to make sure that i am correct but the green with orange goes to the tach driver while the dark green and red go to the signal wires for the safc?? just wanted to make sure they are two different wires.... thanks for your help!

The grey and white wires can be tied together at the same spot or seperated like in the pic. I believe it is shown that way to make it visually easier to understand. If your sensors are not showing anything then you need to test the inputs. get a "AA" battery and connect the ground side to the ground your safc is using, then connect the positive side to your sensor inputs. Your inputs should be reading the battery's voltage which is 1.5 I believe. Please check to make sure the battery is not more then 5 volts!!! If your safc reads the correct voltage on the sensor inputs then you have something wired wrong, if they do not show the correct voltage, the safc is most likely bad. You have my number, give me a call in the evening if you need help with this.
