i'm sorry to say, but that custom kit looks so ghetto as hell. i mean i'm happy for you trying to boost and all to save money, and that motofool didn't actually give you a "kit". but that's what i see. those home depot couplings are not going to last too long, they'll eventually expand,leak and blow off, you need the silicone ones. you got press bended aluminum piping and small and large diameter,for your set up? man try your best to get mendrel bends, you got mad airflow restriction. i don't know man, but i would be more worried about lots of leaking things. that would be a lot of reasons of you not boosting.or check your vacuum connections real well.i know you probably don't have the funds. but if you're going to go for a kit, make sure you're able to do it right the 1st time so it won't give you headaches.
