hey guys i noticed the other day taht my truck was struggling to build 18 lbs of boosy on the daily tune, usually under a load it will build 22-28 psi on the daily tune. so i turned it up to the hot tune where it would usually almost instantly build 25+psi, it would go up to 14-18 and then down to 10 psi almost as if starving for fuel. fuel psi reads 65-72 psi under a pull so its got good fuel psi. also i did a service on the truck becausei was right there at it and no change. i do not hear a boost leak nor do i believe that i have one because of the boost psi fluctuations. if it would routinely hit a number then i would say a boost leak. also i noticed this after changing the rubber elbow at my waste gate which i have ran in very tight. any ideas? i want to say i changed that elbow friday evening and didnt drive the truck until saturday night and sunday is when i noticed the boost issue.
