OK, I have a big 16G, cams, FMIC, AFC, VPC, Walboro 225 HP, etc. I had 550s, and at high rpms in cold weather I was going lean up top at 7k, about .84 on the 02 voltage.
So i got 660s, definitly way more than enough fuel for any 16G.
I installed 660 VPC Chip, so things run fine, and at 6-7k rpm on the AFC, i richened things up,
Drive the car, 7k, .88, so i tried to richen it up to about .92...
guess what, wont go any higher, its like im out of fuel again... WHAT GIVES!!!
Only probs I know of is i have walboro 255 HP pump, and no adj. FPR, ...im runnin 47psi base fuel pressure, but wouldnt that make me go even richer!!
Anyone that can help let me know.
Tom
