Help!!!! No boost

[87LimitedT]

Well today all of a sudden it seemed to surge when I was in it , it would go from 20lbs to 25lbs to15lbs and now it wont even go past 5 lbs and sometimes I get no boost at all, could it be a bad waistgate ?

any type of boost controller on the car? maybe a bad actuator...?

 

[87LimitedT]

its a stock one that some one made adjustable.

I'm just throwing darts here..but I would check that.....check vac lines...puck moving smoothly?

well i took it of and it seems to be moving well and doesn’t seem to have a leak, all of the lines are on tight i , any ideas on what could be causing it not to be boosting any.

Take off the inlet to the turbo and make sure the wheel spins freely and does not touch anything.

checked the turbo has no in and out play but a little up and down spins freely though , could it be the waist gate solenoid could that have anything to do with it?

You can wire the WG shut and see if the car will boost BUT BE CAREFUL as there will not be any boost control.

DO NOT WIRE THE WASTEGATE SHUT!! This is entirely too dangerous to the motor and turbo. They spool a lot faster than you can react. Ask me how I know.

well i ended up just cleaning the waistgate solinoid with some electrical cleaner and made sure it was pluged in good and now im showing 18-20 lbs of boost.
