B20 t3/t4 50 trim turbo tuned on 14 psi has mbc on it. Car has been running good. When I went to drive today maybe been driving 45 mins got on highway. When i went into boost it only went up to 6psi at most on my gauge and won't go over that. Never happen before after inspection Turbosmart wastegate bolts was a little loose. I tighted them up still nothing over 6psi. Can anyone help me out?

 

your fireing ring may have been burnt out after your wastegate came loose... so if its leaking it wont boost right.

you can only use those firing rings once.. cause they act like a crush sleeve...
does it sound like you have an exhaust leak?

Yea it does sound like it has a leak. Also i've been reading about wastegates being stuck open would it being loose make that become a problem? Or is it the ring?

 

Just went out and looked at it again and its leaking at downpipe flange no question about that would that have a influence on anything?

 

yes and get a tial waste gate if u dont have one already

 

Any other input? Double checked all my bolts all tight still only seeing 6 to 7 psi.

 

Anybody else?
