What's your boost d12?

My mistake I missed the part about it being a Volvo forum. I don't pull a sled have never been hooked to one and don't run fast either usually 57 or 58 mph but boy can I go up a hill or mountain.

 

my series 60 will go up to 45 psi all the time and I hate it anyone know how to adjust it?

 

do you d12'ers have an oem boist gauge? my 06 does not. always wondeted. last 95k miles --6.3 mpg

 

Reopening this thread.
Ive finally taken care of the egr valves. Otrperf.

Next, im going to install a boost gauge.

I do still have a pretty big problem with turbo. I just had it off 2 weeks ago, to replace ex mani gaskets. Looked fine, mechanic approved of it. But when im climbing , heavy, i hear a pretty sizable hiss. Only under full throttle . Oncei flatten out, it goes away.

Here is my question tho....is there an actuator on this turbo....where is it?

 

Most likely a leaking intercooler hiss....That's exactly how mine acted.

 

Yep. That solved most of it.

 

nice!

 

Make sure you replace o rings when replacing this pipe. Mine truck was missing the o rings under those clamps. I gues somone before forgot to install them when replacing the flex hose.
