Thanks for checking in! The Dorch stage 2 HPFP went on a black Friday sale, so I ordered one of those so I can feel like i'm making progress while I ponder turbo options.
So it sounds like your mac solenoid is wired to the reflex, and it's basically passing duty cycle from your DME to the mac (but at the 30Hz ish frequency vs. 300 Hz ish stock duty cycle)? I'm thinking of doing that, or potentially just running a boost solenoid right from the DME like hardparker was doing here:

I'm kind of bummed I may have to give up my hope for an internally gated EFR
I'll probably bug Jeff at Speedtech at some point and see if he'd be willing to do an externally gated kit with an EFR since the IG kit seems to be hitting a brick wall. I really like that 4n kit, but I'm having some trouble getting questions about it answered, and i'm a little paranoid about cracking going with a welded 304 manifold. Disclaimer: I haven't heard of any issues with their manifold, I just mean welded 304 turbo manifolds in general
Any thoughts on reliability with welded 304 manifolds? Maybe it's not that big of an issue, but the more I look into it, 321ss seems to be the way to go for longevity.
