Wastegate Question
So I have been looking on here and I have found where some people disconnect the red tube and plug it and others turn the rod in. What is the difference between the two? Is turning the rod in keeping a safety feature and the other one isn't? What are the pros and cons of either of them? I am just not understanding the difference if there is any. Also is this mod supposed to build boost faster?
Thanks

The reason to adjust the rod length is to position the wastegate to its closed position. It is a starting point for the wastegate to be fully closed when there is no pressure on diaphram. Removing the Red tube from the diaphram stops the wastegate from operating.

Both could, depending on if the rod being properly adjusted. Removing the line will stop the wastegate from opening. If it is not properly adjusted ( partly open ) it will loose boost either way. You will get the highest boost if it is in proper adjustment, and you remove the line. I hope you follow me.

Are you having some kind of problem? What boost are you seeing?

Average boost on stock tuning is 15-17 psi, if your having problems with the WG I would recomend a banks bighead WG, and when installing be sure to tighten the rod 7 turns. You could tighten it 7 turns with out the big head and see what happens first. When I disconnected the red line on my factory turbo I didnt see any difference, some trucks do some dont. It turned out I had a massive boost leak because I was only able to make 15 psi with the truck tuned too. Heres a picture of my boot on the lower side of the intake, you can see someone took the spyder off before and didnt install the boots on the right way
Double check to see you dont have any leaks

Rick,
I think he just needs to check the adjustment on the rod to see if it is effecting the boost. Also should check for boost leaks or maybe leaking up pipes, if his boost is low. He didn't say it was low, he just ask about the difference between adjusting the rod ,and removing the red line. I assumed he was just asking. my bad

Thanks guys, I have a big head wg already and I am currently running the banks stinger tunes until I get my dp tuner. With the ww (banks version) I see boost up to around 23 psi. My questioning is how fast it builds boost. When I hit the throttle it takes a few seconds to build boost but when it starts it will throw you back in the seat. I am currently building the boost test jig to test the boots until I replace them in a few months. So my next thought was to test the wg to see if that fixes the lack of low end boost.

The WG being closed tighter will not help the low end boost. To get more low end boost you need more fueling. Once you get the DP you will have better low end boost.
Custom tunes will out do the off the shelf tuners.
