Sounds like you need the Lexus AFM upgrade (with 550 injectors if you can), or the MAFT Pro if you do not already have it.

Check the wastegate.


Maybe is giving you problems. I had the same problem whit my car like 2 months. I changed the wasgate and the problem was solved.

Code 34. This only talk about the turbo but wastegate is a part of the turbo.

Try to change the wasgate or the turbo if you can.
