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.

Code 34 = Boost leak

Presure test the intercooler system and fix the leak

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.

If its a leak in your IC system then I would change all your clamps to T-bolt's to keep this from happening again.

boost leak + damaged WG actuator from shimming.
