This is pretty much my story. Put a greddy kit on my b18, all the vacuum hoses are ran correctly (useing vacum block) checked the wastegate aculator rod, took it off and made sure the flap was working, turbo is working (Just rebuilt 300miles ago) , the kit was on the car previously and has a great tune for this setup.
Big problem after I installed all this, no boost! boost gauge isnt reading any boost at all, tried to drive the car and still no boost, try to get on it the least little bit and spitting sputtering going nowhere.
any info helps....
