Okay.  I am intercooled using factory air-air exchangers so they are "okay"
but will become soaked withing 20-30 mins of hard use like on a road course.
Maximum peak boost will be between 21-25 psi with 21+ psi sustained.

Is an adjustment range of 5-15% (based on mass) too conservative?  What
range would you consider appropriate for this type of setup?  My thinking is
to squirt the minimum necessary to reduce detonation but allow the ability
to squirt as much as is reasonable adjustable based on MAP.  Fr'instance, 18
psi may only require say 5% whereas 21 psi may require 10%.  I just pulled
those numbers out of the air for purposes of example of course.


Thanks,
