I have my order in on a CPR turbo kit 76 / 83, and want at least 9-10 psi to start out. I'm coming from a waste-gated Paxton kit, which is working really well, and it's at 9.5-10.5 psi on E85 currently, and that's the reason I'd like to have at least similar boost from this turbo kit. I see simple manual controllers for under 100 bucks, and then there's the 500$ boost leash controllers and stuff like that. I just want something that'll give me a little more than spring pressure, and kept simple, at least to start off with, lol. Here's one That I liked, seems simple enough , and yet might be able to keep held with a foot brake on the "low" setting. https://www.americanmuscle.com/turbosmart-dual-stage-manual-boost-controller-manu-install.html
