As always my car never works properly for more then a week at a time.. This week its boost falling off veeeeery fast. it used to be at 21psi. Now it goes to about 13psi and falls off consistently until about 4psi when it shifts. So the faster i spin it the less boost.. My vac hasnt changed, Iv checked all the IC tubes for leaks several times and everything appears tight. I hear no boost leaks which i would expect at the rate its leaking out. iv also pulled manually opperated the bypass and it seems to be doing its job...
any ideas what I should be looking at ?
