Does the synapse bov kit from Turner also have the 1/4 inch fitting ? Option for a larger vac line to tap the manifold or better yet connect to the easy Vader mod on the sensor under the cowl? BMW fanatic blogger eliminated his Forge flutter with larger vac line and eventually upgraded to the forge bov from the earlier Forge diverters with vent option. if I hear fluttering from SYNAPSE with 1/8 vac line from manifold i want 1/4 hose from Vader to bov, but does SYNAPSE convert to 1/4 fitting??

Vader ADAPTER 1/4 (louder, less backup fluttering on TURBO wheel)

says his forge bov fits 1/4 " silicone better than smaller 1/8" lines rubber

i have turbosmart plumbback diverter valves on mine... holds 21.5 psi for a year now with no issues, they are on the quieter side though, not as loud as BOVs...20% louder than stock
