Boost controller..?

I've elected to go for an HKS EVC3 (doesn't have fuzzy logic) to control the boost - this will give me more control than the simple 2 buttom approach currently set-up. It also give sme options to lower the boost if I think the car is misbehaving mid-weekend and want to still try and run but at a lower boost. It should also allow me to run boost according to track type/conditions

Not sure what to do with the original Delco solenoid activated by the ecu.>? I know some guys frown on these but for racing they're bloody handy and John Welch reckons they are very useful for race and modified applications.

If I disconnect the original delco unit can I leave in situ or does it have to be removed completely - ie.. remove connectors to etc etc..??

more questions..????
