Single BW s366 (Step in)
This just sounds like bad info... i'm running an S484 on less cubes, with a manual trans... what he's explaining does not happen... period.
here you go, tell me how long that takes to spool up lol

And what was that about loss of boost between shifts???

lol I was waiting for that video... I think if you have lag then you have a shitty tuner!

These show old cast vs the new sxe. You can see the sxe has more of a cupped shape to promote quicker spool.
I've got one on my C10 but it's non-intercooled blow through carb. Running about 9lbs right now. It's a blast to drive!! 
I just about got my dyno setup so should have some numbers in a couple weeks.

It was a 5.3 with a 215/215 112 cam. Made 580 on 17lbs with the non-intercooled carb and 15lbs intercooled. Was a bit lower than I expected but that motor never performed like I expected it too with boost for some reason. Put a LSA blower on it and made 510 on 15lbs, then I pulled everything off it and NA it made 335 so I don't know what it's deal was, lol. I pulled it out and the truck now has a NA 6.0 with summit stage 2 boost cam and is making 380 NA with A Holley Dominator FI. I've got a pair of BW s359/68's going on it this winter.

My '74 K5 2wd has a VS 7875 on my LQ4/6.0 with a 235/231 630/605 114 Tick cam. Never dyno it, but it runs good (7 psi). It's weird that it doesn't really have any turbo whistle like all my S475 did (even before they are making boost) that was on it before.
I considered going to a S366 since it's not a max effort setup.
Crossover is 2.25" piping..... dual 38mm Tial WG's into a single 3.5" downpipe. Decent Treadstone intercooler.
