Vacuum brake system design - switch input needed

[VTtransam]

I'm in the final stages of planning out my vacuum assisted brake system on my 1st gen camaro. Due to my ITB intake manifold on lsx454, vacuum for the brake booster isn't ideal. I've decided to go with the GM vacuum pump to combat this issue, similar to the supercharged builds by Mr. Stielow. I'm looking for recommendations on a reliable vacuum switch. I found a company who custom makes adjustable switches: https://www.worldmagnetics.com/our-s...flex-switches/ but was curious what others were using for a reliable vacuum switch (OEM solution?)

In theory, the switch would kick the vacuum pump on at 17 inHg, and off at 23 inHg. I'm also thinking about running a vacuum canister if space permits between the pump and the brake booster. The sensor would read vacuum in the canister. Hopefully this extra volume would prevent frequent cycling of the pump during autoX and track events. Is this necessary or am I overthinking it?

System components: dual 8" booster with Wilwood 1" bore master, Wilwood Superlite 6R front with 14" rotors, Superlite 4R rear with 14" rotors.

Thank you!
