EBC question
 

I have a question connected with my EBC.
I run a PIT BCU+ EBC (which I know - nobody has heard of before...)
But for my question this is not interresting.

The EBC has a high and a low boost setting.
My wastegate spring is set to ~6.5 - 7 PSI. This is what I would like to run as low boost anyway.
I already had my EBC set to nearly the same value and experienced some shaking (I think because of the nearly equal values of the EBC and the wastegate - is this possible?)

So my plan now is to set the EBC low boost to something really low - like 2 or 3 PSI, so it doesn't affect the wastegate set boost limit and the high boost to something like 10-11 PSI for the beginning. Is this sensible , or what would you do?

Thanks for your help.
