After some more driving experience, I think I know what is holding this
swap back (performance wise).
There is more boost in 1st and 2nd gear; In first the acceleration is
traction-limited, and in 2nd I can actually hit the 15psi max boost,
although that tapers back to about 10-12 by redline.
In 3, 4, and 5th gears, the boost will rise quickly to about 10psi, then
settle to 7-8 psi (base boost). My best theory on this is that the gear
ratio calculator in the ECM (divides road speed by engine rpm) is not
happy with the gearing and reverts to basic boost level. The manual does
explain this process, but it doesn't say how picky the algorithym is.
Driving around with a TechII plugged in would probably point out exactly
what the issues are.
