More GM EGR

[peter paul fenske]

Hello all

Well you can go higher, up to 70 PSI before the injectors start to
act funny, have trouble opening, flow pattern all that. 
Remember 20% increase in fuel pressure only gives you 10% more fuel.

The EGR have been wondering. If a small delay relay is connected to the
egr valve solenoid and used to gnd the thermal switch this might fake out
the ecm. Or a hobbs switch.

Other than that time to get into the code and disable the bit error for
egr. I only have a faint idea how to do this.

I suggest you rob a J car or so of its harness, sensors, and 730 ecm. Gm stocks
a lot of the connectors you might need. GEt the 90-92 5.7 F body calpak
and build the VATS defeat as me and others have posted on this net.
A 280zx fuel pump will get you on your way.

If you tinker with gm make certain you can burn 2732, 27C128, 27C256, and
27C512.
