soooo the lights now show how much timing you have? since knock pulls timing... and not boost... i dont understand how this would make sense? and ill admit ti could be useful for finding vacuum leaks but thats about all i see its good for well and a light show for people to go oohhhh ahhhhh lolQuote:

i will never take my car to a mechanic. ever.
i checked for vacuum leaks and found nothing, but when i unhook the t fiting on the supercharder where the two vacuum lines come together my boost would read full, when i installed the t fitting it will only get to half boost.
your BBV is stuck open.
boost bypass valve right? wheres it located? how do you fix it?
i searched and found nothing about location or how to fix it most threads i found talk about why you should no delete it. nothing on how to fix it.
you can run it vacuum controlled and disable it. take the lower vacuum line off the solenoid (it looks like a mushroom top with a lever going into the blower case) and leave it open to the atmosphere. you can then just cap off the line at the fuel pressure regulator.
the light gauge shows up to twelve bars. That's roughly equal to 174 psi. I'm boosting so high!!!
^^^so if stock 7ish psi gives us an extra 40hp then it will now get an additional 995.385 give or take a few numbers?
what thats alot of HP's hahaha, so unplug the vacuum line coming from the t fitting the the mushroom looking thing and this will have no cons to it?
are there any pros to doing it?
heres a pic is this right
the cons to it are that the car will no longer be able to cut boost under torque management or a couple other times.
i believe you have it right, i dont know how the stock vacuum line setup works since i never had one for the l67.
cut boost under torque management or a couple other times
what is this under torque management?
also i thinks it tcs the button next to the boost gauge, well mine is always off the tcs off light is on and when i push the buttom it never turns on, i think the buttons broke,
could this be causeing my problem, whats tcs for
look for a blown 10 amp fuse under fuse box under the hood. may or maynot be it. is ur abs light on too? torque mag. is to keep from breaking the trans/safety feature for trans.
yes abs is on as well
so should i unhook the vacuum line?
what else could i do to fix the problem the right way?
Could be that or a bad PCM or a bad engine ground

ya i thought that, i found some other threads talking about the same thing but what can i do to fix the boost bypass valve the right way not just unhooking it.
Just replace it with a good used one but the method that was mentioned previously will be fineQuote:

Then get a tuned PCM...it'll get rid of the torque management.Quote:
