must be missing something simple here. Using 2 bar part # su1477 (wells). Drove car yesterday before the os and new map upgrade with no problems. I copied my ve from my old tune to the new one. Map reads 0 until i attempt to start and the it jumps to around 50. using the factory map electrical connection and im running a vacum line from my vacum block (which is directly off the manifold) to the new map. Got to be something simple im missing.
