Bought this triaxle dump in March 1999 Detroit 60 12.7 waste gate is plugged off who knows how long its been like that and don't know why it is plugged off.Will this hurt the performance of the engine (probably). Was going to heat it with my torches to try to free it up and get a new actuator,or a new turbo with actuator.But don't know much on this. Thanks.

Guys plug them all the time and even on cat engines. You get a little more boost and possibly quicker boost. Leave it alone and no it’s not hurting anything. The actuator dumps boost for whatever it is set at. My actuator was factory at 23 pounds. I’m not pushing over 30. If you buy a new turbo down the road with more boost, it won’t even have a wastegate at all

Don't know how much HP this 12.7 is pushing but it's not the quickest thing. Thought it might have to do with the wastegate not being hooked

No gauge. But I will check it out. Wastegate should be open right.

If you do this, plug that air hose going to actuator -
Thanks brother I think the vacuum line or air line is already plugged off. So if it was open this whole time and I close it I should have more HP right.
Cam Roberts Thanks this. -
