Please answer this,

"How do you tune an SAFC with 550cc injectors and the MAF?"
or
What are the steps 1-10 on how to tune with an SAFC and Wideband?

My car drives like crap hitting fuel cut because I cant get the tune right at higher rpms because I am not going to HOLD my throttle at 5,000 rpms for 20 seconds to get the Wideband o2 gauge to tell me its running a 12 A/f ratio at each RPM.

Problem... When I set my a/f % at a certain rpm on the controller, a minute later, the car evens out and changes the a/f ratio.

example, I set the a/f ratio % on the SAFC to +22%, and the A/f ratio is at 12... a minute later, after reving the engine, the car will be at a/f ratio 10 and extremely rich!
