I removed intercoolers and cleaned them out, tons of oil in there. Also cleaned out throttle body and plate. Tightened all hose clamps so I dont think I could have a boost leak. I think the boost is just not being produced due to turbo not spinning fast enough to create the boost. After 4000rpm boost is good and can almost lose traction. But I used to lose traction off the line all the way up to 4000rpm before work done. I am yhinking they put a bug in my ecu. I have kleemann ecu/tcu and should smoke the tires to redline.

Had dealer run codes and diagnose, boost and tranny codes came up: P2001 Charge pressure too low and P2318 One or more messages from control unit N15/5 (Electronic selector lever module control unit) are not available on the CAN bus. (CAN timeout fault) ---both current and stored. Anyone know what I need to do?

Lots of oil? Waste gates working ok? Time to fit a catch can perhaps. Really sounds like your turbos / bearings are on their way...

it was the wastegate. right wastegate was completely open. the rod lost its nut so there was nothing to hold the rod in place when wastegate should close. i put 2 nuts on the end of the rod and tightened very tight so they will not fall off again. I just hope i put them at the right place on the rod, i matched up the amount of threads on the left rod after the nut to the right. if you dont match it right could you over boost that side due to wastegate not opening all the way? still have the trany problem to sort out, anyone know what that code is?

yes, I am getting full power off the line now, I think my tires are too bald and esp intervened too much. TCU reset helped a lot, does not upshift off the line as much anymore. May still have a valve body/electrics kit problem because it still does it sometimes.

When engine is hot and more so when IAT is hot-over 140*F, power is low, either timing or boost is decreased so power is diminished. I have noticed this when it is hot outside and when in traffic idling. You can check for air in intercoolers by opening cap between intercoolers and start engine, only when cold. If hot you will spray hot coolant all over engine bay. Look for air bubbles coming up and pour water in to top so it is at top of filler. You can put a coke bottle 20oz plastic upside down with hole cut in bottom and fill that up. This will move water level up higher and pull more air out. Air goes to highest point in system. Add a trunk mount reservoir tank and hose it to the pump or heat exchanger, this will keep water cooler longer. Can add a heat exchanger also.
