Hi can anyone tell me how to wire-in and route the vacuum hoses for the boost-cut fail safe for the HFS5?

 

Common Guys. Where are the Aquamist Gurus?

 

You need a mac valve to cut boost to wastegate pressure if your using a mbc. The wiring diagram is in this thread: https://www.evolutionm.net/forums/wa...ight=mac+valve. Also, contact RichardL on EvoM and he will help you out with any issues you may have. Aquamist has great customer service.
