Hi, I just put on a new BD super B and I strugle to hit 28# of boost and my egts pulling my empty trailer are out the roof this is on my 2001 and this replaced my HY 35 I checked for boost leaks visualy and tightend clamps and changed fuel filter any insight would be appreciated also the truck ran fine last night on the hys last run

 

have you re installed the j hok or adjsted any other boost limiting device, not familliar with that turbo or its settings, but it sounds like a start, I have heard of the turbo of course, just haven't had my hands on one.

 

no just installed it the way I got it the waste gate does moves a bit with compressed air

 

Try clamping the wastegate hose. I had to do the same thing w/ my HT.

 

I tried that and it did nothing

 

your aem workhorse is clean and not restricting intake ? also, fuel filter fresh and flowin as much fuel as you need to spin that thing? How bout break in instructions, maybe it needs to loosen up a few miles/ hours of operation ????

 

I blew filter out I did not give it a bath I put a new fuel filter in I havent put many miles on it yet

 

and the part about break in instructions ? I know they are meant to keep the top of the workbench cleaned and all, but sometimes they can hold some usefull information...........

EDIT straight from the install sheet on the super b : Take it easy on the turbo for the first 100 miles to allow a proper break in period........ and a part about adding oil to the inlet of the oil passage before starting to at least have some lube on the bearing surfaces and not cause damage on start up.

 

I just went though something similar. My wastegate was not closing all the way. I was only able to build 25# of boost at WOT.....

 

You could make a test plug with a 4" PVC pipe cap and an air chuck. buy an air regulator and pressurize the system a little and look for where the air is going. It might be theres an adjustment thats not right in the wastegate, or you might have slipped a boot on the intercooler. Should be gated at 40psi or so on that thing, right? I know the II PS62 is..

 

I added oil 4 different times during install but still not many miles I will add them tonight I have to go help father inlaw load a truck at 2:30 AM
