Unfortunately the photo doesn't exist anymore, but there are others out there. I had all kinds of problems trying to get the boost up on my mitsu, the only thing that worked was the spring. WG was obviously weak with old age. Now hold 18 odd psi (approx-it's 1/4 to 1/3rd into red), with taper to 12 or 13. this is a weak helper, setting base boost at around 7-8. i also have a 3 bar fpr, and adjusted stop in vacuum module (with around 18 degrees base setting). No apc mods, standard SPG box. I know i could easily go higher by setting higher BB, but i have shredded 2 transmissions in 12 months with lots of good boost (24psi? end of red) from a Garrett, and i have had my fix for now...
