From the GM SPO Service Information DVD for the throttle body replacement on a 2000 3800 Vin 1 engine.
# Install the new gasket, and new inserts and studs if necessary.
# Install the throttle body assembly.
# Install the throttle body retaining nuts and bolts.
Tighten the nuts and bolts to 10 N·m (7 lb ft).
That would be just under the approximately 7.4 ft lbs that 89 inch lbs would equal.
Yes, 17 ft lbs for the supercharger to engine (more accurately to the LIM).
