Didn't want to loose an update with the couple issues I have had recently. It is much better, but not perfect yet.
I am using a combo of the progressive linkage and throttle extension. It now has a lazy roll in which is exactly what you want for everyday driving. The jerkiness at low rpm is gone because all 4 are not firing. I have the secondary jets coming in at 50%. MPG is between 16 and 19 gong to and from work on a combo of back roads and 60 mph driving. Still shooting for the low 20's
The secondaries are consistently coming back to 2/3 percent and sometimes 0. I do still have to knock it down to get it to 0 most of the time. Holley has given me a couple programing changes to see if it works. I will have to play with or get a tune sent to me to smooth out when the two other injectors fire.
Getting happier and happier with it as I iron out the gremlins. I do think Holley should have solved most of these on their end.
