ON some cars it shows its face and goes away and never returns. On some it shows up and stays until one of the two possibilitys is corrected. Unfortunatly there is no blanket answer like "fix this it will go away"

If your not using premium fuel that can also cause issues. If you take your car in for this issue make sure it has premium fuel in it and it is a reproducable issue.

Vernon if you want to pass on what was done to yours thats your perogative, because in all reality your issue has a simple solution that can be done in the driveway

Just to make it clear, when you say premium fuel, you are referring to 91 octane, correct? I've been putting 91 in since day 1.

well I have driven it for a day now and the car is starting to get the hesitation back or rather it wants to fall on its face at full boost. I even moved the bypass off the intake and it still is not acting right. its better but still not right.

some of the ss/tc may have a concern with the boost bypass leaking due to the vib. from the engine because its on the intake manifold. mine acted as though it was the bypass and a repair was performed and helped for a little while and now the concern is showing up again. myself and GM (Gettinausernamesucks) are trying to figure out what is going on and once we do we can then say yes your can has this problem here is the fix or no you have another problem. there is no deff. fix at this time that is why there is so little info. nor do we know if all the concerns are related. but those in the know are trying their very best to find a fix. everyone will be update when info is aval. but we are in the diag stages at this point.

that doesn't mean you don't have the problem or that you do. again once there is a fix myself or Gettinausernamesucks will be more than willing to post what was found.

Let him post the information then, because you do an absolute terrible job explaining just about everything.

there is no info to post at this time other than we are diaging the concern and we will keep you posted. I would not have to explain what was going on (which is nothing more than diag at this point) if you would stop e-thuging every thread you post on. (I am not the only member that has had enough of your line of bullshit posts that are not even about the thread nor do you own a 08 ss/tc. please stop post whoring and leave those with a little insight on whats going on alone.)

I wonder what the long and short fuel trims/AFR/Knock sensor are looking like when it does this boost cut?

Get some datalogging software. It isn't terribly expensive.

Im not having any problems myself, it was just idle speculation. I actually have the Aeroforce scan gages in my car, so if this starts happening to me I can watch whats going on.

Well yeah, but it really is much better to have a timed datalog of what the car is doing.

yeah, something you can recall on the computer and look at there is always best, but the aeroforce gauges can record for 60seconds then playback frame by frame everything recorded, so not as easy to analyse, but possible to record/playback.

I'm glad to report Boostkings ride seems to be happy now. It needed some time to relearn it appears after it was repaired. It seems it got pretty lost in its spark and fuel table learns, a battery disconnect was performed and it seems to be good now.

His car had a leaking Bypass Valve solenoid due to a harmonic induced vibration from the engine.
