I have had a stalling issue when braking not when slowing or coasting or pushing clutch just when hard braking,, my recircs are done that way with a T at the valves. Ive gotten frustrated trying to figure it out and just stored the car in august, way too dangerous to drive.. if you think that could cause the issue I will be tempted to go pull it out of storage and reroute my lines! . we are having perfect boost weather here in TX right now .. but im missing them all :(
