i just bought a blitz boost controller,i have a greddy turbo kit ,i think its an internal wastgate set at 6 or 7 psi,do i need to change the wastegate to set the boost higher,how will it work,please give detailed info please so i can understand about this more,thanks for all the input

 

if you want the boost like above 30 psi then you will probably need to change the base spring, but i am assuming it is the 18g? and it wont be effecient that high anyway, so no. the 6 or 7 psi spring is the lowest you can run. the blitz will increase from there.

may i ask, dual sbc spec r or s or dual sbdic?

 

its the spec s

 

i had the spec r, nice controller either way
