Re: Overboost Issues - HAULN-SS - 11-30-2012
Just noticed this is the first thread in a long time where the person actually had a case of boost rot. That is all.

Got a feeling this could be it, i will take a look later. Thanks again guys, and for not harrassing me about my noob-ness.
Re: Overboost Issues - Ken - 11-30-2012
Well, fuck me, that wasn't it. Any other suggestions? Any other places where a leak could be, or is it just that shitty of a tune?
Re: Overboost Issues - JustinG - 11-30-2012
Does that thing have a legit boost/vac gauge?
Re: Overboost Issues - Ken - 11-30-2012
Meaning the Cobb? I assume it's accurate, haven't really heard anyone say otherwise.
Re: Overboost Issues - JustinG - 11-30-2012
No....does the car?
Re: Overboost Issues - Ken - 12-01-2012
To view boost? There's nothing, I rely on the Cobb. Just hit over boost on that tune, changed to the "stock" tune and hit almost 27. Going to uninstall the the Cobb and see if I can still log. Hopefully it stays within a normal range, if not I guess I will just take it in since its still under warranty.
Re: Overboost Issues - JustinG - 12-01-2012
Do an idle log for a few seconds once the car is at operating temperature.
I lookef at your other log and it seemed like the idle vac may have been a little high. -7 where most say it should be -9 to -11. Makes me think you have a vac leak somewhere. Get yourself a mechanical vacuum gauge.
Re: Overboost Issues - Ken - 12-01-2012
You are correct sir, at warm temps it is idling at -8.2ish with the occasional dip to the 7's. I uninstalled the Cobb, i'm probably just going to bring it in to get serviced. unfortunately once the Cobb is uninstalled i can't run logs or view live data, however i can't see why there'd be any reason why anything would change with that at idle, correct? Either way, i am probably just going to bring it in, i figure if it's under warranty i'll let them do the work. Is there any real imminent danger to the car now? I don't normally go full throttle, at all, so should i be okay if i avoid that?

Don't tell them you installed the cobb, obviously. Say you pulled the battery to reset the ECU in an attempt to resolve this weird check engine light you got this winter.
Re: Overboost Issues - Ken - 12-03-2012
Yeah I figured that, as with any warranty issue, i will just go with the, " i don't know, just started doing that". :dunno:
Re: Overboost Issues - Ken - 12-11-2012
Well, no luck. They weren't able to find anything wrong. Guess it may have just been the tune and the overboost became a real issue once it got colder? I will probably just have a pro-tune done and loaded on the AP.
