If i were to use a Deltagate or Tial WG that has a spring that is set to 10 psi. And if i were to use an electronic boost controller. Is it true that it doesnt matter what psi the spring is set to as long as i got the boost controller? The boost controller can dial in to any PSI i want?

 

yep normally when you want to raise boost.. though ive see description of AVC-R that has a option where you can to low the boost too.

 

so i can just disregard what psi the spring is set to?

 

No the spring is the low setting, period.

 

like it was said you cant go lower then 10 and I read somewere that you shouldn't go more then double the spring because it becomes unstable but I dont know that one for sure.

 

so i should use a higher psi spring and just adjust the boost controller for a lower setting?

 

you can lower boost. ive done it. installed a MBC on an STi and bottomed it out....took it out for a drive and hit 9psi max.

 

 

That's because the wastegate is set to open at 9 psi, dumbass.
