I haven't driven my car in two days and today when I started it up it seemed to drive fine until I spooled up the turbos. When I got on the gas instead of the normal whistling sound that was made by the turbos, it was replaced by a shrieking sucking sound coming from the turbos. Boost is only at .4 kgcm instead of .9. Does anyone know what I should check for? All the pipes and hoses for the intercooler seem to be in place anyone else have this problem before?
