Set to 63 across the board. The flow-bench balanced them all out at 63 so thats what I run. Only other fuel system stuff is a AEM 320lph E85 pump. (Im a big fan of using math and logic to tune. Although I have a great talent for educated guessing when I need to. I once modded an entire maf table with only 5 minutes of driving and two wot pulls sent to me in a data log to tune off of. The entire table was within 6% fuel trims when the guy flashed it :P)
