drove the car today, and i noticed it isnt boost 5psi. i also think the vacuum isnt all that great either...its around 9(forgot what it should read(20)). boost guage is reading 3-3.5 psi.

i made sure my pipes are still together, and they are. what should i check next?

 

Check the boost controller, maybe the settings changed. Check all the lines as well. Check also to make sure everyhting is running properly, like the turbo itself. Any weird things happen to your car latly?

 

Check your hose couplings. My friend was losing about half boost from the turbo and the intercooler last week, and he had a big hole in one of his couplings.

 

i checked the couplings already, everything is ok.

and its not the turbo.

 

Check the Line that connect to your boost gauge, or maby the line near your FPR if u have it taped into your BOV

 

I would think about where you have your vac source ran off of for the wastegate. i had my run to the side of the turbo housing and relocated it to the brake booster source. Night and Day difference.

 

i would say just check ur vac lines... connect the wastegate directly to the intake manifold.... its better that way (i did it and i gained 1psi ). and uhh make sure u're boost gauge is working properly (calibrated and what not).... good luck!

 

you running a missing link?

 

Me Internal Wastegate

 

it is an internal waste gate..but ill try what you people said, and im going to take out the gauge and put it in the motor to see if im getting enough vacuum..9 isnt cutting it...

ill update.

and what does a missing link have to do with anything?
