ok so my car has perfect vacume but when accelerate the boost stays at 0psi and the car has no power. I have check the usuall hoses for leak but everything seems fine. I also unplugged the n75 to check for boost there but no luck there. I dont think the turbos are blown since there is no noice or oil at all. Also the car is running extrimly rich.

Any input will be aprichiated
TIA

the DVs are fine...I did little home getto style pressure test but I coudnt find no leaks. I will be doing normal pressure test tomorrow. Do you think if one of the turbos is blowm?? Even if one is out wouldnt the other one still make atleast few psi og boost ?? or im totaly wrong

thanks for the input guys

then it would throw oil into either the cat or up the pipe to the intercooler...if it threw oil into the cat you would see ALOT of smoke coming out of the exhaust...i'd jack up the car, remove the plastic underbody and disconnect the lower hose to each intercooler if oil comes out you've got a blown turbo, if no oil comes out then it probably isn't your turbos.
good luck
