well after my failed attempt to install a sfmu(broken used pos) i had to reinstall my fmu and run that long vac line. last time i used a tee that was allready there. it went to the vac line going to the ac compressor. not knowing anybetter my fuel pressure under boost(8.7psi) would peg and it took it awhile to get back to normal(55 psi) well that so called tee has a check valve in it. so i changed my vaccum setup and man can i tell a big difference. my car actually feels fast now. and the fuel pressure after boost immediately drops to 55 psi. i haven't had a chance to log my afrs yet but my wideband xm-1 looked good from what i could tell between watching all my gauges and the road. so to make a long story short dont use that thing as a tee for nothing.
