Is My Actuator messed up???

[redmayns]

ok guys i have a gsx with a big 16g for some reason it has a slow spool and when i got to wot, it hits 5psi then completely dies, and i can hear the bov dumping all the pressure. i looked this up it looks like alot of people had the prob but no one posted whether they found a solution or not, this is my second eclipse i had a gst with a big 16g on it and never had this prob, help me pleaseeee, oh and ps. my boost control is off and i'm running stock boost and still not getting any love so it can't be the ebc. thanks

Did you try a boost leak test?

Shimm the wastegate and see if it's the actuator

 

[redmayns]

what do you mean by shimm?

 

[fwdmaster]

what do you mean by shimm?

Adding washers to the wastegate to make the actuator rod more tight so the wastegate flapper can open up

 

[redmayns]

how do i do that?

Is your boost controller "off" as in "turned off" or "eliminated"?

If it's still hooked up, try running a vacuum line straight from the boost source to the actuator and see if the problem goes away.

See if your actuator is stuck. I've seen that happen before if your type of situation. If you're lazy (not saying you are or trying to be rude) but you could just buy one (they're pretty cheap) and throw it on and see if that makes a difference. If it doesn't, well every good DSMer has spare parts lying around haha.

Yeah its the actuator most likely. I had the same exact issue. My buddy had an extra wastegate laying around, put it on and problem was solved.

Use a compressor like you would when doing a BLT, pressurize the wastegate via the same vacuum line you have that goes from your boost source to the wastegate. See what pressure it opens at. If it holds up to whatever it's supposed to hold to (I think 8-10psi) then it's working fine.

Do a BLT.

i see. i thnk it might be my wastegate actuator, the only way to be certain is to change it out so i'mma look into buying a new one

No, the way to be certain is to do this:
