Hey I was looking at the wiring diagrams to repin my 98. and noticed there is an input for spark retard from the abs module for traction control. It doesn't say what the signal is but if it is a simple grnd maybe it would work to spool the turbo on launch or maybe pull timing for nitrous.

It is a PWM signal.
PM me if you want details. I will have to dig them up.
