I'm fond of the idea of simplifying the vacuum lines as much as is reasonable. And I think I'll do the ERG delete.

I have the switchover valve bypassed on my car and I'm not losing sleep over it. The wastegate operates well before the switchover valve should ever operate and the fuel system is pretty well maxed out with the boost fully built anyway.
The blue thing on the wheel well is the vacuum amplifier for the transmission modulator. If it's working, it's worth leaving. It improves shift quality over the VCV directly operating the modulator. You should have 4 hoses on it by the way. Vacuum, Boost, Modulator, VCV.
