Re: Wastegate adjustment help
You're likely spinning the rod inside the canister... which is a good way for it to spring a leak.
Hold the rod with vise grips. Loosen the Jam nut a couple of turns.
Turn the rod end inwards. Retighten the Jam nut.

Re: Wastegate adjustment help
Thanks for mentioning this. Can I ask a dumb question, like how to check if I have sprung a leak in this diaphram?

Hook and air line to the fitting on the actuator and pump it up with, say, a bicycle pump and spray some water, with a small amount of dish soap added, to everything. You're looking for a leak where the rod comes out and maybe the clamp ring.

Cool, thanks for the tip. Guess I'd better get off my ass and give it a shot.

Re: Wastegate adjustment help
Is there a quicker way to do this other than putting it up on jackstands, pulling off the driver side fender and going to work. It's got to be a PITA to make an adjustment, put it all back together and hope you did it enough. Otherwise you go though the process again...

Pull the fender off - adjust - make a pass -adjust - repeat.
*Then* put the fenderwell back in.

Re: Wastegate adjustment help
I use a MityVac pump, and apply pressure to it. (Bike pump with a check valve would work too)
Apply pressure to it, and leave it sit 60-90 seconds. Apply pressure, and watch the rod. If it moves again, the servo didn't hold pressure, and is shot.
Iron clad test- If the canister is off the turbo, apply pressure with your pump and stick the whole canister in a bucket of water. Bubbles= leak.

If you jack the truck up by the frame, so the suspension hangs, you should be able to reach up in there. The heat is going to be the biggest issue. Get some good heat-resistant gloves and give er hell. Or hit up your local junkyard for a shitty fender well, and trim it. It's better then having no fender well at all. Just throw in the trimmed one, go to the track for the day, then once it's dialed in, put the original fenderwell back in.
