NOW THE PUMP HAS A ADJUSTABLE REGULATOR ON IT BUT I HAVE NO FUEL GUAGE TO TELL HOW MUCH ITS PUSHING BUT DONT THINK IT MATTERS CAUSE ITS ONLY FEEDING THE HIGH PRESSURE PUMP. SO HERE IS MY PROBLEM I HAVE NOTICED THAT PULLING OUT I HAVE NOW POWER IF I PUSH THE PEDDLE DOWN THE HOLE WAY IT JUST ROLLS MASSIVE AMOUTS OF BLACK SMOKE THEN AFTER A LITTLE IT FINALLY TAKES OFF ( I DONT DARE TRY PULLING OUT IN FRONT OF ANOTHER TRUCK) IT ONLY DOES THAT WHEN I SMASH THE PEDDLE DOWN IT SEEMS FINE PULLING OUT NORMAL, MY SECOND PROBLEM IS MY SPARTAN TUNER GUAGE READS THAT MY EOT (ENGINE OIL TEMP HAS BEEN RUNNING HIGH ACCORDING TO IT IT STARTS BEEPING AT 230 DEGREES AND IT WILL HIT THAT JUST DRIVING NORMAL DOWN THE TURNPIKE WHAT IS A NORMAL TEMP FOR THE EOT.

Eot should be about 4-6 degrees hotter than your ect. Maybe your truck is in limp mode because of the high oil temp. Sounds like your oil cooler is clogged....

can you monitor the exhaust back pressure and the vgt duty cycle? if you have someone turn the key on and you watch the vgt actuator under the hood you should see it open and close all the way. also if the exhaust back pressure tube or sensor is plugged it will cause this condition of the turbos not spooling properly
