I've been running Mopar Stage 2 kit w/toy for about 4 months now and have suddenly developed a problem. It seems like all of sudden, boost has been hitting over 30 psi regardless of what setting the DAB is set at. I've check for any loose or damaged vacuum lines but I couldn't find any. I've swapped out the WGA and stuck the factory one back in for now. It's peaking at around 18psi only because the factory one is not strong enough to hold the wastegate closed. Anyone seen this happen before? I'm at a lost at what could be the problem. I haven't taken the car in to the dealer yet since they will most likely not cover it under warranty since the Stage 2 kit is installed

sorry to repeat what you already said, but are you 100% sure you've checked all lines?
regardless, if it's running ok boost with the S0 wastegate, don't you think it's possible the S2 wastegate died on you? anyone you know have an AGP or another S2 wastegate they could lend you?

double check the green line coming off the turbo. take you intake off so you can get to the turbo. i had the same problem, looken over all the lines one and happened to find it the second time i looked. it has also happened to a friend if mine without toys.(i have toys) again double check the green line @the turbo.

I've triple checked all the lines, especially the green one that runs behind the turbo. Everything is connected. I don't think it's the stage 2 WGA because even with the stock WGA and DAB at 0, boost is still peaking around 17-18 psi. It used to peak at 9 or 10 psi at the 0 setting. At this point I'm thinking it may be the green #2 solenoid.

you are looken for it to be disconnected. on my friends car we thought it was connected because we felt the rubber connector on the end, but we later found out the rubber broke( sorry i have a dirty mind) :censored: . on my car the line just slid off the rubber hose. all i did was slide it back on and zip tide it on

Same thing is happening to me. My car is boosting to 30 PSI now. Stage 2, no toys installed yet. A couple days ago, it was boosting to 25. Something is getting worse on my car and I can't fuckin' figure it out.

Also, this happened the yesterday:
http://www.srtforums.com/forums/showthread.php?t=80201

Checked ALL my vac lines (including green line) twice...gonna check them again when the car is cool. IC hoses are all good and tight.

WTF is happening? Thinking about putting Stage 0 back in before something blows up.

Anyone have the number for a Mopar engineer? I called a service guy today that I've had install some stuff on my car, and he said, "You'll have to bring it in so we can recreate the problem."

I was like, "So, you are saying that you don't know anything about my car and you want to recreate the problem? Care to pay for it when it breaks?" I don't know anything either, but I want to talk to someone who does know SOMETHING. I don't think any Dodge service personnel will know jack about what to do.

EDIT: Dale might have helped me out here =) Thanks Dale, gonna go check that stuff when the car is cool. I might not need a mopar engineer afterall.

I'm betting that one of the vacuum line connectors is torn, probably one of the really soft ones at the turbo.

If you can do a "leak check", it will be a big help. If you want to make a leak checker, contact GLHS, he'd love to speak with you for hours about it...

If you have a boost controller installed, remove it. It will be nearly impossible to diagnose with it on there.

If you have an el cheapo catchcan, remove it... you want the system as OEM as possible to follow an OEM like diagnostic.

Check all of the connections at the solenoids, look for tears...

Check every inch of vacuum line for a rupture or crack. You can do it by feel. Be sure to check all the way back to the turbo.

That's a good way to start, even though you may be sure you didn't miss a leak earlier...

you have faulty vacuum lines. No QUESTION ASKED!
Wanna test ?

Take the GREEN line and run it straight to the WG, if you get more than ~~7PSI, go and fix your green line.Next come over so I can smoke ur StageII car, in retard mode.

Roc, ignore this post. You have a boost leak :lol:

Boost Leak...!

If you don't find the leak and get the boost back down to 18 lbs you'll be puting a head gasket on that car. :crying:

Boost pressure is simply not getting to the diaphragm in the wga or the wga is broken, or the wastegate itself is stuck or the wga arm is broken.........

Its got to be one of those 4 things

the line that attaches to the turbo broke at the boot on my car too....i saw boost that high as well. kinda scary..especially since it blew off half of the rest of my lines running that high. (now they are all zip tied)

Dale, you da man! :thumbsup: There was a small tear on the vacuum line connector by the turbo. I wouldn't have been able to catch it without doing a leak test. Thanks a bunch!

I've been having the same problem after taking off my DSMBC. I checked all the stock hard vacc lines, and went as far as replacing then w/ soft vaccum hose and even fuel line [to prevent collapse], but nothing. I've since gone back to the stock colored hose and S0 [from S2 w/out toys]. It runs normal on S0 [spikes at 14, holds 9-10psi]. When i put 0 back on I did it one part at the time, starting w/ the pcm and sensors, and then the wga. It was running all shitty even when I put all the S0 parts back on, but a day or two later it was running normal, i guess the PCM had to recalibrate [i'll be trying S2 again one part at a time, but giving the PCM time to get used to the changes]. And yes, I've been reseting the neg battery all the while.

So it's not the vacc lines.
It's not the solenoid.
It's either the S2 WGA [torn diagphragm?] or the PCM has bugged out.

I'm gonna hook up the WGA to a vacc pump today and see if the diaphragm is ripped, otherwise I'll be getting the S2 PCM reflashed. I'll post an update.

Oh, and big ups to all the heads who've been looking out; jason, lewis, dave and that insurance dude from dynoworks [sorry i forgot your name, but your dual side exhaust is fuckin kickass]

hehe, I had my WGA line blow off once, scared the shat out of me. I hit max boost in third tuning the Probec B, and it went from 20Psi to buurying the needle. I nearly shit myself. Well I popped the hood and found the line off. I connected it back and all is well. Like Dave said though, if any one of those soft rubber connectors has a little rip init, it will boost out of control like crazy.
