Boost solenoid set up?
Everytime I have heard this, it has been 100% install error. The vacuum line needs to be dedicated on the intake, no "T's", that will fix the majority of problems with consistency.

Yeah I had an eBoost street in one of my cars, they are a good thing. If it was spiking you may have had it plumbed up wrong.
Top diagram can give you better boost control and allow you to still generate fairly high boost even with a soft spring in it. You can dial it right back for the street and still wind big boost in at the track. The bottom diagram only bleeds boost off the top port, where as the top diagram bleeds off the middle and adds it to the top, kinda of doing two things at once to increase boost.
Simplest option is to do neither of those. Just put the solenoid in line with the middle port. Plumb it so that the two ports which have constant flow are going from the pressure source to the middle port on the gate.
