did this start happening after u installed the parts along with the tune. or did u gradually run into the boost issues?

i would just double check every line and your connections. im sure u already have but if u dont have any leaks it's either a "pill" issue or a tune issue.

could you tell me what is a pill? we changed out the turbo and the fuel pump about two weeks ago.i had some boost then,two days ago we installed the injectors and the tune,after no power.pdx is saying it the turbo,but cant find anything wrong with it pressure tested the system all is good

we also test ran with the labtop and ecutech running it said i only had 1.7lbs of boost

yea, i mean i dont' know what else it could be, he mentioned he did a pressure test and no leaks were found. it could be that or the EBC solenoid. speaking of which i forgot to ask u tvr. what kind of BC solenoid are u running? still using OEM?

yes i had removed the line with the pill in it,and put a diff. line on it.do you think that is the problem?

very well could be, but try it on there first then make it slightly bigger by small adjustments at a time after datalogging of course.

couldn't hurt to try. i know it's fixed some people's boost issues before. good luck with it

if the wastegate arm is tied closed and no boost is going to the selonoid how would it not make boost? Can the ecu somehow still limit boost as maybe the throttle valve as a saftey? I read on the pill however if the wastegate does not open or the line is not on the actuator at all can the ecu still limit boost somehow?
