Hey everyone I got a problem just got my car retuned on Saturday after that drove home everthing was ok on the freeway the next day took the car out to feel the difference I got on the car wot then after that the car had no boost you couldn't feel the turbo nor here the turbo spool and a obvious lack of power I thought it was the 3port put a new one in car ran good again turbo working fine the I got on it again wot and back to no boost again any ideas? I reinstalled the 3 port again and drive it normal and its fine im scared if I give it full throttle or hard throttle I will lose boost again

 

Could be a bad tune, If so it's very critical you need to get this looked at or you could face potential engine problems. (throwing rods ect).

If not check all your intercooler piping/ Vacuum lines / bov. Anything revolving boost. I've had an UICP disconnect and it did that.

 

Thanks for the reply found out my waste gate door is getting stuck time for new turbo

 

could just be a bad WGA, lot cheaper and easier than a new turbo.

 

Its the door its self I pulled the wga arm off and tried to manually move it with my hand and it was stuck till it cooled down then I move it again I can fix the door but what better excuse then to just upgrade the turbo since its coming off
