80tq- lean mixtures/low boost (long)

[Nate Stuart]

I figured as much, but if the line is leaking under boost, then the
boost will show lower than it really is on your gauge too (You mentioned
it was reading lower than you expected), while the pressure in the IM is
higher, and the ECU also senses a lower boost pressure than in the IM so
less fuel=lean.

Just shootin the dark.
