Although I've heard that even he doesn't have the right jig to get an 870 turbo just right. Maybe things have changed with that ?? call him and see. 678-588-6197

Okay thanks, i will check them out, one more question, when the truck is cold and hasnt been started the actuator arm is supposed to be in the up position correct?

if u crank up the truck with the control actuator off of it you should be able to press the control arm down, and it should move back up on its own fairly easily from the exhaust pressure against it at idle. If it hangs up, or especially if it hangs up in the full down position then something is wrong with it.
