I am running the four blade riffraff diesel compressor wheel.

When putting everything back together I accidentally unplugged the red vacuum line for the wastegate actuator. I went for a test drive and I hit about 31 or 32 pounds of boost. Pulled it back into the shop and check everything out once again and noticed it was unplugged. So I plug the line back in. With it plugged in I can only hit about 23 PSI. I don't tow very much but when I do I would like the extra psi. But I'm unsure if it is just wasted energy having it unplugged or if I actually am benefiting from hitting 30 PSI or not?

According to diesel site, they say not to exceed 32 PSI for long amounts of time for the best turbo life. But I've also read online people saying about 23 or 24. I'm thinking that the manufacturer probably knows best, not saying that we don't know anything about it but seems like they created it so they would know ??

Also seems like when it is unplugged my turbo will boost up to pressure easier, i'm not planning on the hot rotting my pick up

 

 

Exactly as it says, "extended periods of time". How long do you intend to stay into hard throttle runs. Normal driving is not going keep boost at its peak. You'll be fine. You could always leave it the red line off and plugged , but lengthen the rod slightly if you are concerned with too high of boost at WOT. It sounds like you are okay where you are at now.

 

Yes I think I'll be OK, I just wanted to be sure thanks a lot
