Thanks. I don't know how I missed that post. Makes sense and is pretty cool to see 10hp from a few flow mods.

I'm going to document my non-sequential setup now, and then compare it to the 8374iwg. I'm at 1.25bar on the twins, I think that's perfectly achievable with the 8374 on E20, same as now. Let's see the trade-off of non-sequential vs proper single.

Now with EFR turbos and newer ECU's it just doesnt make sense to go non-sequential. Its a cheap alternative that just lessens the driving experience. I took some videos this morning of me in 4th gear on flat ground starting at 2200 rpms with my street ported REW to see what rpm my EFR 7670 on base map PFC would hit 10psi. It was right at 3000rpms. Since you say on paper things can look different than reality I challenge you to do the same test with your Non-Seq car. I love that you did this test but it went against everything you still believe. I have had a ton of fun in Non-Sequential FDs and hurt a lot of buddies feelings in other cars with that setup. I dont hate it, it is just a step backwards from seq twins or an EFR single setup.a
Ill attempt to upload the video but with my computer skills we shall see.

I am sorry to keep this going, but it brings up a question that I've had a hard time getting an answer I can understand. Awhile ago I was running on just the primary as I was having an issue with the sequential system (I had the damn pre controller plug reversed). I guess that would technically be a problem with myself and nothing to do with the system... anyway, the car made a solid 12 psi. It was holding it's own on the track, but I was wondering how much power I had lost without the secondary online. I had a couple "knowledgeable people" tell me not much power is lost as it is at 12psi. 12 psi is 12psi. I am guessing these people don't take into the account efficiency? Like the charge temp itself? 12psi with both turbos kicking should result in a much cooler charge resulting in a more cfm correct? Am I looking at this wrong? If I have that right then why would the non sequential make more power on the top end vs mid range? Is there more flow through the manifold the way it is modded? What am I missing? I would think maybe the non would pick up some mid then taper back off to equal the sequential. I need to go review cfm vs psi again I guess.

That's kind of what I was thinking on the power. These are the sp so not sure if that makes any difference. so that brings up another question since at the same time I was having a slow leaning condition while holding WOT for long duration. Would it be possible the EGT started climbing since it was on a single turbo? Heating up slowly? Possibly causing the very slow leaning condition?
