I adjusted the VCV, advanced it a bit so that the vacuum would be more in line with the new power curve. With the VCV where it was I had great full-throttle shifts, but at light throttle the VCV was allowing the transmission substantially full vacuum as if there were little engine power, and I'd get flaring. Advancing the VCV about half of its adjustment range cured it. I don't seem to have any full-throttle slipping so haven't adjusted the modulator (again the video, you can hear good balanced shifts). How much did you turn your modulator adjustment? I am curious how much adjustment is necessary to make the shifts more sporty-feeling.

No smoke = good, agreed. However, since I'm running 18psi and you 22, it seems that there is more air available and therefore I can add more fuel if I want to try it, ... and increase boost accordingly.

Light powerbraking is where I started, if you watch the video you'll notice that as soon as I hit 3000rpm & get good boost the speedometer jumped to 20mph, had to release the brake and go to save the new Michelins (plus the crowned road was sending me sideways). I like your numbers better, but with an extra 300lbs and 5.5mm elements, I'm not expecting to keep up. The changes I've made so far in the new engine have made driving this car a completely different experience, so much low-end grunt that it never had, throttle response like a gasser, yet with short-shifts it has such smooth torque (yes, I even lengthened the Bowden cable for earlier shifts), it feels more civilized like the Prevost and its big Detroit w/ allison, it is quite enjoyable to drive. No more mashing the loud pedal and waiting for downshift and boost. More power is there I'm sure, but this is already such a grin, even with 2.65:1 gears it spins fresh 215 rubber.

I've read accounts of turning the full-load up beyond 1.5 turns, only went 1 turn. I figure I can always try more, but not this week I think I'll get the car out and put a thousand or so miles on it as-is first. I need to do some more reading and calculating so that I fully understand the interdependence of all of the pump's adjustments and linkages.
