So i installed a missing link for my 420a turbo, and i had some questions for anyone who has ever ran one of these on their setup. First of all, when installed it creates huge drop in vacuum on my boost/vacuum gauge, because the small hole on the side of the unit acts as a vacuum leak. Not sure if this is normal. Second of all, the engine runs extremely rich sometimes while driving not under boost, around 10-11 AFR. Lastly, the engine also runs very rich while on deceleration, for example going down a hill and leaving the car in gear, without the missing link it runs lean like normal, but just the opposite with it installed. It seems to do its job perfectly however for going into boost, my engine doesn't hit fuel cut anymore and moves from vacuum to boost very smoothly. But as for everything else it just seems odd and not sure if it's normal or even safe for my engine. Please share your input! Thank you!
