Hey Jim looking forward to seeing what you do on the Corn.As for AF ratio here is a graph of the 6.12 run as you see AF is all over the place but that run felt real good and I think the reason it did not shift to high was because it RPMed so fast the Shifter did not have time to reset.The red line in the middle is AF also I m set For Gas so actual Ratio is not right I Just didn't see any reason to Change .All my Stuff is mixed and Ebayed Junk so my pump came with the Hi11born Stacks and is too big I'm using Rons barrel Valve and Nozzles. I had a Rons set up which I tore up the pump and it had 30 Nozzles and a 95 pill. this is what we ran in my uncles car on methonol and we went down to 16 nozzles for E85. He is running a 105 pill. This is working great for him I am running the same Nozzles and a 120 pill. I need to make more runs but I think I will Need to go up on nozzle size because I am running 120 psi which is high.
