I just installed an SP57 and am interested in using a Manual Boost Controller, instead of my EVC IV. I don't want to overboost on the stock fuel and I've heard that the MBC's are better at controlling boost. Just for those that don't know how SP sets up their kits I have a HKS GT wastegate and BOV and no nipple on the turbo. How do you route the Vaccum hoses and who makes a good MBC? Or can i make one from scratch?
Thanks
