I just fit a VF34 turbo on my01 wrx, it is running at 20psi, is it correct or 15 is correct? So am I wrong?

 

20PSI definately aint correct, you should be running lower than that, id say the 15psi is a better margain but you want to speak to John Banks really... 20 is too high.
I should also state that running a turbo that your car isnt mapped for can lead to serious engine reliabiliy problems, ie it can blow it up.

Yes my car not mapped yet, although it is not easy to reach to 20psi, but how about normall VF34 boost, I just fit it yestoday in scooby maina, you mean if later the ECU mapping will slove this problem? Or it is still a strange thing, I need to speak to Scoby maina?

 

Connect the compressor outlet directly to the wastegate actuator to run only 8 PSI until it is mapped.

 

just 8 PSI? So I need speak to ScoobyMaina to change it to 8 PSI? Is that you mean?

 

Sorry, I want know can adjust it by myself or I need speak to Scoobymanina, and is it very dangerous?
