Currently I have my EBC and boost gauge referenced to my manifold but I would like to try out referencing my compressor housing. I found the below diagram (first picture) and it seems like it would work fine. My only question is, am I running the risk of boost spiking by not referencing the second turbo? Ie. the unreferenced turbo spools faster than the referenced one and reaches boost faster than the controller can compensate for? Other issue is waste gate opening early on un-referenced turbo due to building boost faster than the referenced turbo causing the controller to be behind on the counter boost pressure, causing lag. Would it benefit to T the two compressor housings together prior to hitting the solenoid? See second picture (altered by me).

I've run mine both ways, currently have a line from each compressor T'd into 1. Can't tell any difference between the two ways. No boost spikes or difference in lag with either set up.
Okay, thanks for the feedback. I went ahead and individually plumbed each waste gate and it seems to be working well. Smooth pressure build and zero spike.

EBC routing question TT
