ok i think i got the hoses down. so how do i do the 3-4 psi on the fine adjustment which is the top? how many turns is that? and the same with the coarse, which is on the side?

 

1 full turn of fine = ~1psi
1 full turn of coarse = ~3psi

 

ok. i have it all hooked up right. first test drive it said 8 psi. so i adjusted the fine screw and then the coarse screw like cincy said. i then had it up to about 16psi. i pulled over, readjusted the coarse screw some. now it was at 21 psi. so i pulled over one more time to get it around 23-24 and readjusted the coarse screw again a little. and now when i drive it hits 15-16 and it sounds like the dv is giving out or something, it just wont boost any more, sounds like a boost rev limiter or something lol through all gears it does it. i then pulled over and tried to back the coarse screw off a little, nothing. ideas?

 

Forge lists the springs as:

Green - 5-15 PSI
Yellow - 15-23 PSI
Blue - 23-30 PSI

i have i think the spring that came with it with the spacers in.

 

Most run with the green and both spacers, you can also try the yellow by itself. You should of only gave the b&s about an 1/8-1/2 turn so you dont pass 24psi. Make sure your dv is working properly and you may need to reset the ecu.

 

i changed the spring to yellow. i readjusted it a little bit. it seems to work great now, crazy more throttle response, spools up faster. peaks at 21-22 psi. it seems if i turn the coarse a turn or a half of turn, it doesnt do anything to the boost to try to raise it to 23 or 24.

 

YOu might wanna use the bleed for the last psi or 2 to make sure you dont spike higher. now you know why so many people love mbc's. You can only adjust the mbc so high above the spring pressure of the wg.

 

its at 21 psi now, i move the coarse screw and it does nothing to the boost to raise it.

 

use the bleed

 

used it. at 23psi. thanks.
