Why do you think your AFC is pulling your timeing?

What octane of race gas did you use?

I run an AFC and my timing on pump gas is 18 degrees at 7000 for 21 psi on 94....I put some race gas in and the car just loves it and timing only gets better.

Nice numbers guys.
The AFC is not pulling timing, but I am on the wrong timing map because the AFC is pulling out so much air. My timing is hitting 17* by 6000 rpm, thats where it usually drops 1 or 2* then it might come back up to 15* by redline. I used 94 octane all day. I may have had a heat soaked MAF or water temps may have risen a little during the pull......but I assume it to be caused by a little knock. My Karmen reading after each pull was just under 2400 Hz each time.
