ok so i just installed my BR 35r and i ran a vac line from the MBC to the side wastegate nipple. the nipple on top of the wastegate is vented with no cap or vac line. when i started the car it was extremly loud and i noticed that the external dump tube was dumping while the car was idleing. this is my first time running an external dump on any and was wondering if this is normal. still havent ran the car into boost since i dont have a tune for the 35r yet. AFR was between14-17 at idle and normal when driving the car around off boost. so my question is if the sound is normal and what do i need to do with the top nipple on the wastegate. Thanks
