So, I read months ago about disconnecting the red line from your wastegate, and so i got curious again a couple days ago...
I was wondering who all has done this and if so how they capped off both the wastegate and the end of the line, and also the boost increase numbers
-thanks
Do a search on it and you wil find a lot of guys that have done it. The numbers and "Ideas" on if you should plug the ends can be answered. Taking off the red line will help....Numbers??? That is where your truck will make the difference. Some trucks will make a big increase...some wont. Some guys said it hurt there fuel milage so they put it back to stock or got a better waste gate controler. when I get some free time I am going to purchase the Turbo Master Waste Gate Controler from Thedieselsite. In my opinion I think it is the best way to go comparing to the red line idea. JMHO

I just recently did this and it made a difference for me. Normal driving it seemed to build boost quicker but no higher numbers, 4-7 lbs in normal city driving. When i was having some fun i was able to get 20 lbs of boost now, before i pulled and plugged the red line i could only get 14-15 lbs max no matter how hard i stepped on the throttle. Even got a little black smoke doing a burn-out lol

Alright, so i pulled it off and drove down the road, went from 22 to 29-30 psi... Now i'm just gonna have to find some good plugs. gonna see if it helps pulling a sled and also with mpg's. Thanks guys
Yes it is possible to blow the boots off, however that happens mostly due to older boots that have been collecting oil. They may also be loose.
I personally would not run a stock turbo with those high of boost numbers. The stock turbo wears out quicker anything above 25 plus it is no longer efficient at higher numbers.
Do a search and you can find that info.
I have used the Turbo Master controller. It works very nice.
Set it at 25 and enjoy!

You can modulate this a bit with a plastic T setup which will bleed some but not all of the signal. Start with the T uncapped. If that doesn't lower it enough, try a cap with a small hole. Then increase the hole size.
Has anyone done this before or did I 'discover' it first?
Do you have to cap off each end of the red line after you cut it?? I pulled the line off and my boost did nothing.
And what is the address to deiselsite?? I tried going there and it would not come up??
well hope you did not cut the red line. But just pull it off. Some people have plugged it...I have not. If your truck is stock the boost wont crank way up there. With a tuner you can peg it whenever the right foot gets heavy. Check out the "links" tab. Then go under "Sponsor" and you will find Dieselsite.com. Should try to fill out your Signature so everyone can see what your truck is/has. It helps everyone else help you. I call it 'Redneck-Bling'....

So do I plug the actuater and the end of the red line or do you just take the red line off and leave it alone?? Sorry if I sound stupid with this but there wasn't even a slight change when I tried this. I also filled out the signature, saved it and its not coming up???
