Ok you can see my setup, I cant get the turbo to run less than 44 lbs boost . And from a stand still WOT my egts will hit 1500 by the time Im running 80 mph. I know the stock turbo needs to run 35 lbs max. what can I do to help my problem???Please any advice???

I don't know a whole lot about 12 valve trucks, but does the waste gate move?
My waste gate was stuck on my 24v when I got it and boost was through the roof.

thats what I was thinking, do you gets yours broke free??

You're pushing a pretty good amount of fuel. Did you ever get your hp figured out? I'm still guessing it's over 330. Does it feel like that much? Maybe time for a turbo upgrade or at least housing upgrade to help with egts. Check your boost elbow. If it's fully closed then open it up a little. Try a 1/4 to 1/2 turn counterclockwise at a time.

Yup, but I got mine fixed free too. It was under warranty.

try taking your boost valve right out and put the stocker in and if your still getting high boost check your wastegate

No havent figured my hp out yet. Im thinkin about 330, from 0 to 80 a 2500 4x4 6.0 powerjunk is about 5 car lengths behind me, thats all I have to go off of. And my allen head on the tst valve is about to fall out its so loose. My afc is about centered, but my plate is still forward. I need to pull it back. with my allen head 1 turn out on the sts valve it ran 48 lbs, and I have only gotten it down to about 42. I was pullin 7000 lbs today with the cruise on at 1900 rpms and it was runnin 900 degrees. how bad is that? and the hp topic, it will spin the wheels right before shifting into 2nd on dry road with no spool up at all. Im gonna try to get it on the dyno tomorrow if I get off work early ebough. And thatk yall for the help, Im learnin alot.

900 u can run all day. I think u can run up to 1200 or so constantly safely. Anything much above that only short burst's at a time.

rootremblay

thats a relief, thanks

provided you have the probe mounted PRE turbo...

gyman98

900's perfect if your preturbo, sounds like your wastegate is seized

rootremblay

moved my plate back and Im runnin 37 lbs WOT and the temps are a little lower. And my probe is pre turbo on the rear half of the manifold

Box5

37 is much better. U can adjust ur gov arm to get that to about 34 which would be good.

rootremblay

I slid my plate back a little more, now Im at 34 WOT. But is there anyway to lower the boost with the plate where it was?? how do you adjust the gov arm? is that the arm that has the little clip that you have to take off to get to the pump inspection plate?? or should I leave it be?? how much boost does a stock truck like mine run?? stock has a 180 pump.

rootremblay

is it possible that im only letting it fuel enough to get 34 lbs max and the wastegate still isnt opening. And can they be taken apart and cleaned or just buy a new one?
