I was wondering if its possible to force the bypass valve into an open position after reaching a certain boost level. For example i was considering a custom twin charge system and i would need the bypass to open as soon as the turbo boost kicks in.
Is this acheivable with some type of manual boost controller for the s/c itself?

 

It is possible, but I'm not exactly sure how you accomplish it.

 

bump for any more info?

 

I have a 05 s/c balt an was wondering how to check the boost bypass to see if its bad or just go around it completely cus i have a 2.6 pully an i have checkd for leaks an been to a tuner an i cant get past 18lb. An its fluttering when boosting.

 

u donn get any flashing cel's by any chance right ?

 

You can unplug the line that goes to the little black soleniod on the side of the valve cover. That's what the PCM uses to limit boost. If it still happens, then it's not the computer, the valve itself may be bad. Look up "boost bypass mod" for instructions, it was discussed many times on here.
