The ECU is telling you that it doesn't care for the shimmed wastegate.

Code 34
* The turbocharger pressure is abnormal.

Trouble Area

Turbocharger
Air flow meter
ECU
Intercooler system

Code 43 is something totally unrelated in all likelyhood.

* No "STA" signal to ECU until engine speed reaches 800RPM with vehicle not moving.

Trouble Area

Ignition switch circuit.
Ignition switch
ECU

Well, unrelated unless your ECU is going Tango-Uniform.

Most likely you've created a boost leak. Check all of the couplers you've moved and those near them for tears and make sure they're securely fastened.

Okay... doesn't really change what you need to do as far as diagnostics is concerned.
