Vaccum at idle ?

[OverBoostinGST]

what is the vaccum on the boost gauge supposed to be at idle? mine is reading 10

 

[Boostedexcel]

between 17-19 Hg

do you think i have a boost leak then?

between 17-19 Hg

Yup thats where I had it on my old 2g AWD

ya think i have a bad boost leak at my BOV' then because i checked for leaks ( not with a tester ) but by ear and my bov hisses pretty bad, i think that can explain the jerking i get at WOT , and it wont go over 3000 rpms when i floor it

 

[dalatinromeo]

Wheres the hissing coming from the off the line or the actual BOV?

Perform a boost leak test if you suspect a boost leak. Keep us posted

Yeah it should be around 17-19. Unless you have cams, cause with my web cams my vacuum is around 11.

Well a vaccum/boost leak would definatly explain the jerking at 3K problem. Make and hookup a leak tester. http://www.dsmtuners.com/forums/showthread.php?p=1746901#post1746901

Leaks can only be found with a tester. Be careful with the previous link as it's for a TO4E compressor cover. If you still have the stock turbo, use this link instead.

ya sounds like u have a bad leak if u can hear it. u dont need a tester to hear it if its that bad. car will jerk around if u are losing air and will pull timing if u leak bad at wot. if u dont have cams in the car then ya u should see more vacuum. with cams though u will see less vac due to increased valve overlap

This still doesn't get you off the hook on boost leak testing just so you know, what's with you kids and laziness these days. If you want to get into the business of modding your DSM then do it right, get use to the idea of leak testing. Someone would have to hold a gun to my head and force me to take my Talon off my driveway before my leak testing after any work done which involves the intake tract, and I mean any work.

I'll have to get back to you on why we're lazy these days....


Jerking at 3k:
Check the condition of your spark plugs. NGK BPR 6ES gapped at .028" with good wires and a good coil pack.
AFTER you test for the boost leaks of course.

You're a government worker, you're suppose to be lazy.
