way out with the SAFC. Working on nistune to fix this. SAFC alone are kinda bad. Changing MAF singnal one way will increase timing. Less air flow > computer thinks less load> so it throws in more timing. When your tring to lean out the car, your tricking the ECU that there less MAF signal > to put in less fuel > causing the side affect of increased timing.
I'll also eventually be experimenting with this on my NA with nistune to see if removing the intake T on a NA can provide any gain or none.
