DIY Switch activated Boost controller

[YoYo_4G63]

I want to do a "home made" Boost controller activated with a EGR VSV solenoid and i have a question.

*My Tial Spring is 15psi as low boost setting and the mbc is set @23psi*

In this mode (picture below) i have to keep the switch On to by pass the MBC and keep my car at low boost.

So i was thinking on doing this (picture below) to keep my low boost setting with the switch and solenoid OFF. someone think that check valve will stop boost going backwards?

I know you wanna do something different but i see the problem being that you wanna be able to quickly switch how much boost but how are you going to switch your maps for the tune at the same time..
my car is tuned for 22psi like 500hp if i turn up the boost it gos down to like 400hp..
3 things to look at when you wanna make power Map Table Fuel Table Timing Table.
if i run 15 psi in my car its pulling 12-13 degrees timing which is bad.. but 7-9 at 22psi and 6-7 at 30psi
alot of factors come into play for inefficiency.
check out my walk around video look what i did to switch up the boost/tune quickly.

Ok i dont need to change maps the car is set for 22+psi i just want to keep low boost with the valve off instead on for 15psi

I would use something other than that kind of valve

Most of the EBC have the scramble mode or a switched boost so can you not run a 2 stage ebc that has 2 but preset at 2 boost levels? Unless you have link then you can run 2 settings switched anyway

I guess i have to check this on my own. I'll post results of this later
