Glen,
	What is the benefit of this WG modification when the CPU's
boost cut-off limit (1.3 bar) is unchanged from stock? Does the boost
now reach the 1.3 bar limit quicker due to the weaker spring? I have
an '87 5000 CSTQ as well, and am wondering if this WG mod might improve
performance without spending the $795 for IA mods. You don't have IA
mods on the 5000, do you?
