Paul,

	I am guessing here, but I suspect that most of that 1 sec 
improvement comes from a higher efficiency system (due to the lower 
outlet temp on the IC), and only part of it from the 1psi extra boost.

	What is the 30-70 improvement at your regular boost level, with 
the sprayer on?

	Thanks.   Good work.
