So you were getting extra air through them, but no extra fuel?
That would cause some problems for sure.
Yes. When you install the progressive linkage you find the percent of TPS where the secondary's open and program that in. So at 3 5 or 20 percent the secondary's do not fuel at all unless its a 1 to 1 ratio.
When the secondary's hang it allows additional air through which confuses the sniper.
I know the blades are centered. I have added the wrap on the spring. I think the solution for smooth drivability is a combination of the extended and progressive linkages. I will have some programing to do once I iron out the blade sticking issue.
