Hi all,

I recently installed a coolingmist meth kit in the car. Empty tank, injector located in black plastic hose connecting to the intake.

Installed at the same time, the zeitronix boost sensor, EGT as well as a labonte boost solenoid.

I also installed a grimmspeed solenoid. Flashed the car with a map configerd for the solenoid.

After completeing the intsall, the car would only boost to 15psi. Checked for leaks, nothing...

Started to trace back my steps. Took off the labonte solenoid, nothing. Took off the grimmspeed, reinstalled the MBC and reflashed the car to the previous map. Now after all the changes, the car will not boost at all!!

Now I have all these gadgets on a car that will not perform...

How do I test if the wastegate actuator is faulty?

Any help with what might be wrong is greatly appreciated.

 

Did you put the MBC lines on backwards your only boosting wastegate pressure.

 

check your cat. my cat went and i couldnt boost past 9 psi. i went with ur test pipe and im boost creeping with 3"tbe. but the car moves again lol.
