What are peoples AFL reading on your SAFC? I was reading about 50% at full throttle in fifth going about 120. It usually reads about 20-30% just cruising. Just curious to know what other peoples are.

 

Yes it doesn't ever read 100. I've had the same thing going on in two other FCs besides my own. The most i've seen was around 68%.

 

With a stock intake system & fairly free flowing exhaust, I can bump 50% on my S4 NA at WOT at high RPM.

What were the mods on the one with 68%? I would think you'd need significant work to get that much airflow. ... unless it was a turbo.

I hit 82% during a 2nd gear pulls regularly, saw 83% once during a cold night

 

True duals, K&N intake and stock manifolds/engine

 

Damn! Very nice, yeah I have a modified stock air box, K&N filter, and a main cat replacement pipe on my S5. Still much room for improvement for me. Good #'s guys.

 

Go to the afm. Push the cone all the way back with the key to ON and observe what the reading is. See if it will go to 100percent. If it does, then I'd repeat going from full closed to full open several times and at each end I'd hold the cone there for a minute or so. I'm guessing it might be a learning experience for the SAFC. Just guessing.
