Hey there, Im trying to install a boost controller, just a simple gfb, manual bc. Afaik the bc goes between the wastegate nipple and the one that goes back to the turbo ? The thing is the nipple size from the boost controller is a lot larger than the nipple from either of the ends? How to I over come this dillemma ? bit confused here. Cheers

 

I used another bit of pipe as a sleeve for the smaller nipple then put the larger pipe over the top and secured it with a jubilee clip. Seems to work ok...
